马上准备填I-539和家属转B-2，发现有几个问题拿不准，恳请赐教。我在去年9月底递了I-140 和I-485，到现在没批，下面是表格中的几个问题：
Answer the following questions. If you answer “Yes” to any question, explain on separate sheet of paper.
a. Are you, or any other person included on the application, an applicant for an immigrant visa?
b. Has an immigrant petition ever been filed for you or for any other person included in this application?
c. Has a Form I-485, Application to Register Permanent Residence or Adjust status, ever been filed by you or any other person included on the application?
f. Are you, or any other person included on the application, now in removable proceedings?
g. Have you, or any other person included on the application, been employed in the U.S. since last admitted or granted an extension or change of status?
Thanks in advance!
