Question

Where does Congress get its power to regulate naturalization?

Answer 1

The Constitution vests certain exclusive powers in the House of Representatives, including the right to initiate impeachmentproceedings and to originate revenue bills.

Answer 2

Congress gets its investigative powers from Article I, Section I of the Constitution. Legal experts largely agree that it is an implied power (not explicitly stated). Because Congress is responsible for crafting legislation for the nation, the better informed they are, the better legislation they can create.
