part 4的
7。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?
8.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?
这两个怎么填阿？我现在用H1-B，难道要付上original H1-B?
