网上说,交了485之后 如果opt/F expire 了,就自动进入AOS,在这种情况下,"Cap to Gap" rule for F1还适用吗?
-Yes as long as you file the H1 petition before the OPT expires.
就是说我现在opt,交了485, pending,opt8月过期了(变成AOS了吗?),4月1号申了H1B (COS), 但是10/1才生效,
-Because your OPT change to H1 is pending, your status is not 自动进入AOS (you are in pending status, not AOS). Only if you have not any non-immigration status, then you 自动进入AOS.
之前的opt还能自动cover9月的gap吗?
-Yes.
