It depends - You can file your tax return but you will not be able to include your son as your dependent without an Social Security
Number (SSN) or Individual Taxpayer Identification Number (ITIN).
To apply for an ITIN, you would use Form W-7 and would need
to attached your tax return to this form.
Please note, you will not
qualify for the Earned Income
Credit (EIC) without a valid Social Security
number (not an ITIN) for yourself, your spouse (if filing jointly), and any
qualifying children.
