but what about travelling outside us after aplying for i485, once we have a valid AP everything is ok ?????
yes, this is right. if you are out of status for less than 180 days, it is okay. you can adjust your status in USA. in my case i was out of status for 178 days. i got my GC approval last month. while my case was under process, i used my AP twice. no problem. as long as you are out of status less than 180 days, you are safe.
good luck.
