This is exactly what I am worrying about.

This is exactly what I am worrying about. My hu*****and has got Green card through NIW as main applicant. While mine is still pending due to name check. My hu*****and wants to quit his job to do something else. If he has no job, what will happen to my green card application? Why they ask for her hu*****and's employment verification letter (he already got green card)? Could some experts give us some advice? Thank you very much.
