someone (USC) who didnt file tax for the past 2 years (2021-2022) got RFE for i-864 when he filed for his mother 2 months ago.
situation :
1. he didnt make enough for the past 2 years
2. he need joint sponsor ( that he never submit in the initial submission)
3. this person said " i had a business and i lost / didnt make money. therefore i didnt file tax"
i told him to go to CPA to file that tax 2021-2022. and suddenly voila, he can produce tax return report that he got from CPA.
he cant produce tax transcript, something about website is closed for the moment to file tax ? ( not clear), but AFAIK, even when u lost for ur business, u still need to file tax no matter what, even when he finally got joint sponsor who made more than enough.
