ANSWER

If your spouse is a nonresident alien and you file a joint or separate return, your spouse must have either a Social Security Number (SSN) or an Individual Taxpayer Identification Number (ITIN). ... If your spouse is not eligible to get an SSN, he or she can file Form W-7 with the IRS to apply for an ITIN.
