回複：a wierd question about AP and 485

While during status adjustment (I-485). If your H1 is expired, you can use the EAD to continue employment. No need to the H1 extension.

AP- even you have a green card. You still need this document to travel for more than 3 months. While in I-486 stages, my advice is- try not to go away for too long.

you can go to INS website
