Acturally I did read the linked posts in your blog, but I am still confused respecially regarding the H1/AOS. In your post it said:
＂AOS/H 双态＂不准确，还给人以误解，以为自己可以在 AOS/H 中任意选择。今天使用了 EAD 就是 AOS，明天不用就还是 H.
读过＂绿卡申请过程中的身份调整＂一文的同学已经清楚，从非移民身份到 AOS 是单行线。只是因为 H 具有 "Dual Intent"，所以还可以由 AOS 返回来，－－通过移民局的申请或重新以签证入境。
--if I have H1 but use AP to re-enter, do I void my H1, and do I have to regain H1 by re-applying for H after I re-enter US?
H 的 "Dual Intent"，就是字面上的意思。H 身份可以有＂双重倾向＂，－－即移民倾向。
在申请签证时，VO 不能因为 214(b) 而拒绝 H 签证；在入境时，不能因为进行了移民申请，而拒绝以 H 身份入境；在境内进行 H 的延转时，USCIS 不能因为开始了移民申请而否决其申请。
在移民申请开始之后，H 可以不需要 AP 就可以离境并再入境；使用 AP 入境还可以继续使用有效的工作许可；
-- Is this "工作许可" EAD or H1?
在进入 AOS 之后还可以回到 H 身份，这些都不影响其移民申请。
-- Can I return to H status automatically after using AP (which leads to entering AOS), or do I have to re-apply for H1 to reclaim H1 status?
I guess my question is: should I apply for H before or after I use my AP? There might be some differences between the two scenarios? I know someone who re-entered with AP and continued to work with H1, but it seems this post suggests tne need of reclaiming H1 by re-applying for it once the AP is used?
About the re-entry with AP within 30 days after the denial of I-140/I-485, I just wanted to re-confirm. I checked some other sources, it seems that is true.
Thanks again for your advice.
