The IRS will issue you an ITIN if you are a nonresident or resident alien and you do not have and are not eligible to get an SSN. To apply for an ITIN, file Form W-7 with the IRS. It usually takes about 30 days to get an ITIN. Enter your ITIN wherever your SSN is requested on your tax return.

Note. An ITIN is for tax use only. It does not entitle you to social security benefits or change your employment or immigration status under U.S. law.
