My bio appoingment is on this wednesday as far my process is there still a chance of an RFE?
I have been its only been 3 weeks since i submitted my I-751. Already got my NOA 1 anr Bio appoinment. Even though the process is going quickly im still not conftarble untill they send me the green card letter. Is it ok to panic?

You wont get an RFE unless the adjudicator requests something, so there is no predicting an RFE.

You can get an RFE up until the point that you have your green card in your hand. There is no way to know when they will or won't send an RFE.

You shouldn't panic about it though, everyone is in the same situation!

Get an RFE even green card in our hand??????????? is this a joke?

so I should still worry i mean i dont have anything to hide i just want to live in peace and get over this process already it feels exactly like I felt 2 yrs ago when i filed for the AOS

Why exactly are you so worried about an RFE? Did you forget to include something in your packet? If yes then you can get more documents ready in case you do get an RFE. If you do get an RFE just send these. If you did not forget anything in the first place quite worrying. As MarkNAshley said, you can get an RFE at any point, till the time you get your green card.

RFE is not the end if you have nothing to hide. Yes it will complicate your life but I think most people who get an RFE get their green cards eventually.

Good luck
