1.递交i-140表多久可以批下来?
-Case by case, normally several months.
2.可以将i-140和485表,还有AP一起递交吗?
-Yes for EB1, not for Eb2/Eb3 for Chinese born applicants.
3.如果2.可以的话,是不是意味着我可以拿着回美证回大陆呢(我的H1b身份到2012年5月过期)可以回多久?
-Correct. AP is valid for one year and that means you can stay in China less than one year with AP.
谢谢。
