(R7) I have a "green card" and have lived in Texas for several years. Am I prohibited from purchasing firearms and ammunition from an FFL in Texas?
As long as you are not otherwise prohibited from purchasing or possessing firearms and ammunition (for example, a felon), Federal law does not prohibit you from purchasing or possessing firearms or ammunition. However, you will need to put your alien number or admission number on the Form 4473 and provide the FFL with documentation establishing you have resided in Texas for more than 90 consecutive days preceding the transaction. Moreover, you must make sure there are no State or local restrictions on such a purchase.
