I-485 pending and after 6 months (so AC21 portable). Laid off. H1-B revoked but I-140 not revoked. Since it was very hard to find a job in US, I found a job outside the US temporarily in Sept 2009 and stayed there till now. Can I still enter US on AP?
The way I see it, until and unless your AP or 485 is revoked, it is legal to use both.
