詳情是這樣。
1. 在A公司用H1B幹了半年，跳B公司。
2. 在B公司用H1B幹了三年半，期間：
一年後I-140獲批。
三年後，延H1B三年。這樣到終止日期累計H1B超過六年，不過因為I-140已批，沒問題。
3. 在B公司三年半後跳到C公司，恰好排期到了。H1B轉換隻申到一年。但H1B累計隻用掉四年，
還有兩年可用。
-Not that case.
我困惑的是，明明140是在B申請的，到C要重新辦PERM，H1B轉換時也隻能延一年嗎？
-If the approved I-140 from B is not withdrawn by B, you can use it to extend your H1 for another one year or three years (depends on PD current or not). If B withdraw the I-140, you can not use it to extend your H1 anymore. Thus, you have to have an approved I-140 form C to extend your H1 (using premium processing to get the I-140 approved before your current H1 expires).
我H1B還有兩年才滿呀。
-It is not the same as the 6 year H1 duration anymore. Every time you extend your H1 now, you have to provide the approved I-140 to be qualified for the H1 extension. Whether you get one year or 3 years depends on whether you rPD is current when USCIS make the decision.
如果我當時沒告訴C的律師，B的I-140已批，是不是就可以拿到兩年了？
-Not that case. Enven if the lawyer asked for 3 year H1 extension beyond the 6 year limit, USCIS would have only approved the H1 for one year because your PD is current when USCIS made the decision on the H1 petition.
