US Immigration from Barbados

My grandma left the US in 2018. She already had permanent residence filed by my USC mom. My grandma was ill and couldn't travel, then the pandemic hit. 88 years old and alone through this whole thing. We did not get a re entry permit but my aunt has gone to get her. We have a doctors note notarized saying she couldn't travel. Will she be let back into the US?

TIA

Considering everything going on how long is it taking to receive biometric appointment?? Filed in feb 2021. Is it with all service centers? Mine is Dallas

Hello all. I am new to this forum and I am happy to be here to share my experience and get positive feed back. I have a question.

I filed for my mother 2/9/2020. On 2/10/2021, I received a RFE about my birth certificate. They could not read it well enough from the uploaded snap shot. I sent an original which they received on 3/3/2021.

No updates after that. I am checking daily. My case is in the Potomac Service center. Can that be the reason for the delay due to the amount of applications they receive ? Should I call USCIS and see what is taking them so long?

I do appreciate the answers.

Thank you.
