US Immigration from Myanmar

Hi everyone, my conditional green card will be expired on December 9th,2020. When I should apply I-751 and please share any experience about what to and how to prepare the package, thanks in advance.

I petitioned my wife on an IR1. I petitioned her son on an IR2. They are both here now. They have green cards. I have been married to my wife for five years. Her son will be 16 next September. I will complete his adoption next month.

Will he get automatic citizenship? How does that work? What must be done?

Is there anyone from MYANMAR? I married US citizen 2 and half year ago and now I'm in US with my husband for over 1 year. We filed visa for my son and now the case is at NVC. I have some questions for embassy interview. I divorced my ex-husband (my son's father) in 2006 and he passed away before I remarried to my current husband. I have both certificate of divorced and death, but I heard people are saying that consular might ask permission letter from grand parents to allow my son to come to USA. That will not be easy for me to get since I lost contact with that side so long ago. Can someone share experience with me,please? I need to know those people who recently took embassy interview at US embassy Yangon, Myanmar, thanks in advance.

I have been anxiously waiting for my EAD to arrive for the past two weeks but still no update so far. I got a temporary work permit through my student visa until mid-December, and was hoping that I'd get my EAD by now. I'll officially be outside normal processing time by Monday. From other people's experience, does calling USCIS or submitting an inquiry help at all?

I just noticed today that EAD/AP process time at National Benefits Center has gone down drastically - from 6.5 - 8.5 months up until yesterday to 2.5 - 5 months as of today. The receipt date for inquiry outside of normal processing time is now March 3, 2019. That change sounds too good to be true. Is there an error in the system or the NBC has actually caught up with three months of EAD/AP applications in a matter of one month (assuming they update it monthly)?
