So I got approved December 30th. my question is I got a letter saying I got approved for I-821D on top of the letter says I-795. Am I going to get another letter about 795 or that means I got approved for both?

I got my bio appointment for nov 29 at 11. Can I be able to go before the 29th is there any problem if I go before??

My sister got a letter saying: The principal application could not be accepted for the reason(s) specified on the Notice of Action (Form I-797). Therefore the processing of all applications cannot continue. The form I-765 is staple with this letter. We don't understand what's wrong?

Thank u guys!

Yes she send those forms

The application/ petition was filed on an outdated version of this form?

Why or how us lost it?
