如果暫時不談申請H1或者綠卡的事情，女方這次先用J2入境美國，找到Offer後直接換J1，這個過程需要Waiver嗎？
-No. But if you stays with j2 for more than 6 months, you can not change your J2 to j1 within US and have to go outside US to get the j1 visa to come back to get the J1 status. Of course, if your J2 status is less than 6 months, you have no problem to change it to J1 within US.
我怎麽看到網上有帖子說07年之後有規定在美國境內由J2轉換身份為J1也要Waiver（J2持有人需要離境2年），是這樣嗎？
-I've never heard it. Here is a statement from: http://www.hooyou.com/j-1/j1_2year_rule_faq.html
"Ben wants to change from J-2 to J-1 status. Once he obtains an IAP-66 (Certificate of Eligibility), he can change to J-1 status in the U.S. However, he may be subject to the two-year Foreign Residency Requirement restriction twice, once as a spouse of a J-1, and again as a J-1."
另外， "J2---->J1" 與 "J2+EAD"，兩者相比，哪一種方式更容易、更劃算？
-"J2+EAD" is better because you do not need to get two times of J waiver(one is your J1 and another is your spouse's J1 plus your J2 waiver).
