System of Government: Practice Questions & Explanations

The U.S. federal government has THREE branches, established by the Constitution to provide CHECKS AND BALANCES so no single branch becomes too powerful: (1) LEGISLATIVE BRANCH — Congress, which consists of the Senate (100 members, 2 per state) and House of Representatives (435 members based on state population); makes laws. (2) EXECUTIVE BRANCH — the President, Vice President, and Cabinet; enforces laws. (3) JUDICIAL BRANCH — the federal courts including the Supreme Court; interprets laws. Any ONE of these is acceptable on the USCIS test. The terms 'legislative,' 'executive,' and 'judicial' may also be used. The Department of Defense and military are part of the executive branch but are not 'branches' themselves. The Federal Reserve is an independent agency.

There are 100 U.S. Senators — exactly 2 from each of the 50 states, regardless of state population. This equal representation in the Senate was a key compromise in the Constitution (the 'Great Compromise' or 'Connecticut Compromise') ensuring that smaller states would have equal voice in one chamber while the House of Representatives reflects population. Senators serve 6-year terms, with one-third of seats up for election every 2 years (staggered). Senators must be at least 30 years old and U.S. citizens for at least 9 years. The Senate has unique powers including ratifying treaties, confirming presidential appointments (Cabinet, judges, ambassadors), and conducting impeachment trials. 435 is the number of voting House members; 538 is the total electoral votes for president.

U.S. Senators serve 6-YEAR terms. The Constitution sets this longer term so the Senate has more stability and continuity than the House. About one-third of Senate seats are up for election every 2 years, so the Senate is never entirely new — providing institutional memory. There is no term limit; senators can serve as long as they keep winning elections. The 17th Amendment (1913) changed the original system (where state legislatures chose senators) to direct popular election. Compare: House members serve 2-year terms (more responsive to voters but less stable); Presidents serve 4-year terms with a 2-term maximum (22nd Amendment); Federal judges including Supreme Court justices serve for life ('during good behavior').

The President of the United States serves a 4-YEAR term. The Constitution set this term length in Article II. Originally there was no limit on the number of terms — George Washington voluntarily stepped down after two terms, creating a strong tradition that lasted until Franklin D. Roosevelt was elected to four terms (1932, 1936, 1940, 1944). In response, the 22nd Amendment (1951) limited presidents to two elected terms, or a maximum of 10 years total if a vice president takes over with less than 2 years remaining in another's term. Presidential elections occur every 4 years on the Tuesday after the first Monday in November. The inauguration of the elected president takes place January 20 of the following year. The candidate must be at least 35 years old, a natural-born U.S. citizen, and a resident for at least 14 years.

This question's correct answer changes whenever a new President takes office. USCIS provides interviewers with the current correct answer at the time of each naturalization interview. As of May 2026, applicants should check the USCIS website or call USCIS directly before their interview for the current correct answer. The applicant should know the FIRST AND LAST NAME of the current sitting President. Similarly, three other questions on the 100-question test change based on current officeholders: the Vice President, your state's U.S. Senators, and your state's U.S. Representative. Speaker of the House also changes. The USCIS recommends checking these specific questions close to your interview date because political offices change with elections.

The Constitution gives the FEDERAL (national) government certain ENUMERATED POWERS, including: (1) print money (only the federal government can create currency); (2) declare WAR; (3) create an ARMY and military forces; (4) make TREATIES with foreign nations; (5) regulate interstate commerce; (6) establish post offices; (7) coin and regulate money; (8) establish naturalization rules (immigration/citizenship); (9) establish federal courts. Any ONE of these is acceptable on the USCIS test. The 10th Amendment reserves all other powers to the STATES or to the people. State powers include: provide schooling and education; provide protection (police); provide safety (fire departments); give a driver's license; approve zoning and land use. Some powers are SHARED (federal and state both can do them): tax, build roads, make and enforce laws, establish courts.

Under the 10th Amendment of the Constitution, powers not delegated to the federal government nor prohibited to the states are RESERVED to the states or to the people. State government powers include: PROVIDE SCHOOLING AND EDUCATION (most public schools are state and local responsibility, though there's federal involvement); PROVIDE PROTECTION (state and local police); PROVIDE SAFETY (state and local fire departments); GIVE A DRIVER'S LICENSE (each state issues its own); APPROVE ZONING AND LAND USE (local government primarily, under state authority). Any ONE of these is acceptable on the USCIS test. Federal powers (printing money, declaring war, making treaties) are NOT state powers. Some powers are shared between federal and state governments: taxation, building roads, making and enforcing laws, establishing courts. The American system of FEDERALISM divides power between the national and state governments.

The CABINET is made up of the heads of the 15 executive departments plus the Vice President, who together advise the President. The USCIS Civics Question 37 asks for two Cabinet-level positions. Any two from this list are acceptable: Vice President; Secretary of State (foreign affairs); Secretary of the Treasury; Secretary of Defense; Attorney General (head of the Department of Justice); Secretary of the Interior; Secretary of Agriculture; Secretary of Commerce; Secretary of Labor; Secretary of Health and Human Services; Secretary of Housing and Urban Development; Secretary of Transportation; Secretary of Energy; Secretary of Education; Secretary of Veterans Affairs; Secretary of Homeland Security. Cabinet members are nominated by the President and confirmed by the Senate. They serve at the pleasure of the President — they can be dismissed at any time. Most Cabinet-level offices oversee large federal departments with thousands of employees.

As of 2024, the Constitution has 27 AMENDMENTS. The first 10 amendments, ratified in 1791, are called the BILL OF RIGHTS. The most recent amendment, the 27th (about Congressional pay raises), was ratified in 1992 — though it was first proposed in 1789. The amendment process requires two-thirds approval from both houses of Congress and ratification by three-fourths of state legislatures — a deliberately high bar ensuring amendments reflect genuine national consensus. USCIS Question 27 (65/20 list): 'How many amendments does the Constitution have?' Answer: twenty-seven (27).

THE SUPREME COURT is the highest court in the United States. It is the final authority on: the meaning of the Constitution; federal law interpretation; disputes between states; and cases involving federal questions. Nine Justices serve: the Chief Justice of the United States and eight Associate Justices. They are nominated by the President and confirmed by the Senate. They serve for life (subject to good behavior) or until they retire or are removed through impeachment. USCIS Question 39 (65/20 list): 'What does the judicial branch do?' — Related question. The specific question about 'highest court' is Question 40: The Supreme Court.

The two major political parties in the United States are the DEMOCRATIC Party and the REPUBLICAN Party. The Democratic Party's symbol is the donkey; the Republican Party's symbol is the elephant. Other parties exist (Libertarian, Green, etc.) but the two major parties have dominated US politics since the mid-1800s. USCIS Question 46 (65/20 list): 'What are the two major political parties in the United States?' — Answer: Democratic and Republican.

The Constitution: SETS UP the government; DEFINES the government (its structure and powers); and PROTECTS the basic rights of Americans. USCIS 65/20 Civics Question: 'What does the Constitution do?' — Accepted answers: sets up the government; defines the government; protects basic rights of Americans. It establishes the three branches (legislative, executive, judicial), the system of checks and balances, and (through the Bill of Rights and amendments) guarantees fundamental rights and freedoms.

The two parts of Congress are the SENATE and the HOUSE OF REPRESENTATIVES. USCIS 65/20 Civics Question: 'What are the two parts of the U.S. Congress?' — Answer: the Senate and House (of Representatives). Together they form the bicameral legislative branch. The Senate has 100 members (2 per state); the House has 435 voting members (based on state population). Both must pass a bill for it to become law.

CONGRESS makes federal laws. USCIS 65/20 Civics Question: 'Who makes federal laws?' — Accepted answers: Congress; Senate and House (of Representatives); (U.S. or national) legislature. Congress is the legislative branch. A bill must pass both the Senate and the House, then be signed by the President (or a veto overridden) to become law. The President (executive) enforces laws; the courts (judicial) interpret them.

The PRESIDENT signs bills to become laws. USCIS 65/20 Civics Question: 'Who signs bills to become laws?' — Answer: the President. After Congress passes a bill, it goes to the President, who can SIGN it into law or VETO it. If vetoed, Congress can override the veto with a two-thirds vote in both houses. This is part of the system of checks and balances between the legislative and executive branches.

The PRESIDENT is the Commander in Chief of the military. USCIS 65/20 Civics Question: 'Who is the Commander in Chief of the military?' — Answer: the President. Under the Constitution, the President leads the armed forces. While Congress has the power to declare war and fund the military, the President directs military operations as Commander in Chief — another element of the separation of powers and checks and balances.

The two parts of the U.S. Congress are the Senate and the House (of Representatives). This is one of the 65/20 civics questions for older, long-term residents. Congress is bicameral, meaning it has two chambers: the Senate, with 100 members (two per state), and the House of Representatives, with 435 voting members apportioned by population. Together they make up the legislative branch that writes the nation's laws. Knowing that Congress consists of these two chambers is fundamental system-of-government content, included in both the standard and 65/20 versions of the test.

The President signs bills to become laws. This is a 65/20 civics question. After both the House and the Senate pass a bill, it goes to the President, who can sign it into law or veto it. If the President vetoes a bill, Congress can still make it law by overriding the veto with a two-thirds vote in both chambers. This process illustrates the system of checks and balances. The President's role in signing legislation is part of the executive branch's function and appears in both the standard and 65/20 civics lists.

The two major political parties in the United States are the Democratic and Republican parties. This is a 65/20 civics question. These two parties have dominated American national politics for well over a century, though other minor parties also exist and participate in elections. The civics test asks applicants to identify these two major parties by name. The Federalist and Whig parties are historical parties no longer active, so they are incorrect. Knowing the names of the two current major parties is standard system-of-government content on both versions of the test.

The judicial branch reviews and explains the laws — it interprets the laws, resolves disputes, and decides whether laws agree with the Constitution. Any of these is an acceptable answer on this 65/20 civics question. The judicial branch is headed by the Supreme Court. By contrast, the legislative branch (Congress) makes laws and the executive branch (the President) enforces them. Through judicial review, the courts can determine whether a law or government action is constitutional. Understanding the judicial branch's role in interpreting the law is core system-of-government content.

A U.S. Senator represents all the people of their state. This is a 65/20 civics question. Each state has two senators, and they represent everyone who lives in that state — not just members of their party or only the voters who supported them. This is a key principle of representative government: elected officials serve all their constituents. Members of the House of Representatives, by contrast, represent the people of a specific district within a state. Understanding whom senators represent is part of the system-of-government content on the civics test.
