Can I be an immigration sponsor with Social security disability?

Yes you may file the Petition for your wife and you will need to also file an I-864 Affidavit of support. If your income does not exceed 125% of the Poverty Guidelines, you can try and meet the Public Charge test with three times the amount in liquid assets. If this is still not enough then you will also need a co-sponsor who makes enough money. If you would like a consultation on the facts of your specific case feel free to contact me as indicated below. I do charge for consultations but whatever you pay for the consultation would then be a credit toward the fees for your case if we are retained for services after the consultation.
