Question about EB-1/1 sun1052008-02-03 07:11:50

I heard from someone that EB1-1 (the first priority) applicant can submit I-140, I-485 and labor certificate application at the same time, is this true?
Thanks for any information and comments.

EB-1a does not need LC, what do you mean?

Thanks for your response. Then, what does LC mean?

it's labor certification you mentioned in the text.
