2008 test · Question 94 of 100 ★ 65/20
What is the capital of the United States?
Official USCIS answers
- Washington, D.C.
Why this is the answer
The U.S. Constitution set up a federal district, not a state, to be the seat of the national government. The city of Washington was built in that district, so the capital is Washington, D.C. It is not part of any state.
💡 Memory tip: D.C. stands for 'District of Columbia' — the capital's own federal district.
