老公OPT，我F1想申请Eb1a
1. 是不是老公先file I-140？如果批准我再跟着一起file 485？
2. 如果是这样，填I-140的时候，Part7中配偶及子女信息是不是也要填我的信息，但
是选项
applying for adjustment of status 选 no
applying for a visa abroad 也选 no
3. 如果是file Eb1a，没有雇主支持的，I-140 part.4中第7和第8项都怎么填？是填No吗都？
Is the petition being filed without an original labor certification
because the original labor certification was previously submitted in
support of another form I-140?
If the petition is being filed without an original labor certification
, are you requesting that USCIS request a duplicate labor certification
from the Department of Labor?
另外要准备材料中需要labor certification吗？
