Your credit card has already expired. You have the option of applying for naturalization before receiving your new Green Card. When you receive your Form I-90, Application to Replace Permanent Resident Card, you must submit a photocopy of the receipt.

You Are a Citizen of the United States if and Only if You Meet the Following Criteria

You were born in a territory of the United States and have a birth certificate from that territory. If you do not have a birth certificate from your birth country, you may be able to demonstrate your citizenship with other documents. You were born outside the United States to at least one US citizen parent, and your parent(s) registered your birth with the US Embassy or consulate in that country.

If your birth was registered before the age of 18, the Embassy or consulate issued your parent(s) a document proving your U.S. citizenship. This is referred to as a Consular Report of Birth Abroad (CRBA or Form FS-240)
