A co-signer can have their credit affected if the borrower defaults on a loan and the co-signer do not make the payments. Co-signers can request payments from the borrower directly, but it may not be easy to collect. A co-signer can also request to receive monthly statements from the lender to verify payments are being made, to review the due balance, etc.
If you need to file a tax return but do not qualify for an SSN, you should apply for an ITIN. If your dependent does not qualify for an SSN, but you want to claim them on your return, that person will also need an ITIN.
Both resident and nonresident aliens can get ITINs, regardless of immigration status. The bottom line is that you may apply for an ITIN if you need to submit a tax return, even if you live in another nation.
