google了一下Eb1b, Perm拿到綠卡後180天內換工作對綠卡及今後入籍的影響，把感覺
較權威的說法整理了如下。。。
pjiang 說( http://blog.wenxuecity.com/myblog/14332/200807/22543.html )：
"""
其實，並沒有任何的條文規定，拿到了綠卡之後不能馬上更換雇主，更沒有 180 天之
數見諸文本。這完全是為了自我保護，避免 fraud 的嫌疑及將來入籍時可能引起的麻
煩。
...
在入籍申請時，有誰因為拿到綠卡之後迅速離職而被拒？老師未曾聽說。
"""
但同時又說：
"""
在拿到綠卡之後就迅速地離職，雇主告不告你並不重要，如果移民局因此而認為有
fraud，那才是麻煩。
"""
有點不明白，既然沒有聽說有誰因為拿到綠卡之後迅速離職而被拒，為什麽又提到“移
民局因此而認為有 fraud”，怪嚇人的！
下麵的說法更嚇人了（ http://immigrationvoice.org/forum/forum5-all-other-green-card-issues/3305-changing-company-after-getting-green-card.html ）
"""
Clearly, the law before AC21 was passed in October 2000 required that a
person continue working with the employer that sponsored the green card for
at least 6 months to 1 year after obtaining the green card.
...
The official rule (which IMHO has not changed with the passage of AC21) is
that you must not have any preconceived intention to leave the job when you
get your Green Card. (Your friend clearly does :-( ) In general, working for
the company for one year after getting the GC is normally considered
sufficient.
