看这个: In the I-131 instruction, page 4: E. If you travel before the advance parole document is issued, your application will be considered abandoned if: 1. You depart the USA; or 2. The person seeking advance parole attempts to enter to USA before a decision is made on the application. 在看这个: In the I-485 instruction, page 10: Effect of departure from the USA while your application is pending 1. Applying for adjustment of status under section 245 of the ACT If you apply for adjustment of status under section 245 of the Act, traveling anywhere outside the US (Including brief visits to Canada or Mexico) will lead to the denial of your Form I-485 as abandoned unless: A. You are an H, L, V, or K3/K4 nonimmigrant woho is maintaining lawful nonimmigrant status and you return whith a valid H,L,V or K3/K4 nonimmigrant visa; OR B. You obtain, before you leave the USA, a grant of advance parole by filing Form I-131, Application for Travel Document, as specified in the Form I-131 instructions, and you are paroled into the USA when you return. 我的理解:如果ap发下前人已经回国,你的AP申请自动放弃,你的485申请被认为自动放弃 还是拿到AP卡之后在回去吧!
