I am holding 工作签证 and am losing my job. My I-94 expires at the end of 2013. People recommend my applying for B visa to keep my status. I have a few questions：
1). If B is approved and I get my job later, is it bothersome to get H-visa again? How long does it usually take? - Processing Dates
2). After I-539 form is submitted to immigration bureau, is our status legal automatically？ - Yes, “合法身份”与“合法停留”
3）Should my kid (a dependent) apply for B visa? Is it better for him to apply for F-1? Or we don't need to do anything with him？ - Your family members' depedent status will also be invalid upon your status is gone invalid, automatically.
Thanks.
