现在的情况是月底走人，而另一家的Offer 还没来。
-You had better not leave until the new employer to file the H1 transfer.
HR 人告诉我：你一走，我们就得向移民局报告。因而：
问题1：我是不是应该在H签证失效时，接着申请B2。
-You may file B2 before you leave the current employer if you can not do the H1 transfer. If you do not file B2 and not file H1 transfer before you leave current employer, then your H1 transfer approval may not have I-94 and thus, you need to go to China to get the H1 visa to come back.
问题2：B2 申请交上，就算合法逗留，是从邮递日期开始算还是从移民局收到申请开始算？
_"从移民局收到申请开始算"
问题3：如果B2申请刚刚交上，另一家的Offer来了，这时比较好办，取消申请即可。如果B2签证已被批准，事情有点麻烦，
从B2转回H签证，加急办理约需多久？
-<15 days.
问题4: I-539 表有几问，我不知填得对否, need to confirm with you (Background: we have been F1/F2 visa holders. We only applied for and got our current H1/H4 visa. )：
(1). part 2, Q2: "Is this application based on the extension of change of status already granted to your spouse, child or parent?" (I think it is NO)-Correct.
(2). Part 2, Q3: "Is this application based on the separate application to give your spouse, child or parent an extension or change of status? (I think it is NO) -Correct.
(3) Should I include my 17-yr old kid as a co-applicant? (I think it is YES)-Correct. You and your child can use one I-539 for both of your change of status and pay one filing fee.
多谢你们。常常感到谢字不能表达我们的心情。
