Earlier this month I saw a question on Money.SE asking whether it was possible for a US non-resident to open a bank account? I thought that question was confusing as it didn't specify whether the US non-resident alien was living in the United States or not. A more interesting question I think would be the following:
Non-resident aliens living in the United States are able to open bank accounts. Suppose a non-resident alien living in the United States falls out [immigration] status. What happens to the bank account and to the money in the bank account?
