回复：请问换工作从L-1B转E3或者H1-B，最短需要多长时间？

请问换工作从L-1B转E3
-3 to 5 months.
或者H1-B，最短需要多长时间？
-Normally 2 to 4 months, but if you use premium processing, you can get it approved within 15 days.



还有几个其他的问题：
在等待新的工作签证的期间，我还能为我前雇主工作吗？
-Yes as long as your L1 does not expire yet. Otherwise, you can not work until the E3 or H1 is approved.

2010年的H1B还有名额吗？
-Yes at least until the end of this year.

朋友告诉我移民局可以提供加急服务，请问具体怎么操作呢？
-Only h1 has the 加急服务.Pay $1000 more by filing I-907 (your employer need to do that, not you). E3 does not have "加急服务".

可以在美国境内申请吗？
-Yes for both E3 and h1.
