Immigration and Bankruptcy
"The Congress "The Congress shall have power.. to establish a uniform rule of naturlaization, and uniform laws on the subject of bankruptcy throughout the United States.".
This clause gives the Congress the responsibilty both to set the terms under which immigrants can become citizens; and to pass a set of laws, that will apply throughout the United States, to establish under what terms and individual or corporation may discharge his or her debts. It is interesting to note that the framers considered bankruptcy important enough to include in the Constitution.
