回复:回复:另外请教245(i)和MTR for I-485是什么意思?
MTR is Motion to Reopen. You can file MTR after your I-485 is denied if you think USCIS denial of your I-485 is unreasonable/unjustified. It is similar to Apeal.
It seems it is difficult for you to win the MTR because your status did have a big gap unless you fix this gap.
