thanks @fireworks8 for the answers.
wow! lucky you! still i find it hard to believe. as of now, as i see on trackitt, you are the only person having a PD of 6/30/2014 in EB2 and who has received the GC so early as compared to folks like me who have a EB2 PD falling in December 2013. :-)
as i understand,
01: you always stayed with EB2, right ? i.e. you never went for a downgrade to EB3, correct ?
02: based on the EB table B ( meant for filing ) in visa bulletin for April 2022, you became eligible for filing AoS ( i.e. I-485 ) with USCIS, right ?
03: meaning for your I-485 ( based on EB2 ), RD: 4/7/2022; ND: 5/5/2022; biometrics: 5/23/2022 as you already mentioned, right ?
04: in that case as you have mentioned, what is the I-485J ( please notice the "J" ) filing about ? can you please clarify on that ?
thanks for your patience and congrats again!
