Your attorney's advice sounds pretty solid but you have to factor in life conditions. You may not be able to work for a long duration or multiple long durations while your immigration petition is all sorted out. You might be granted an Employment Authorization card intially while your application is pending but then if the application is rejected, triggering the need for a waiver, you might have another long time not being able to work. Make sure your US spouse knows everything that he or she is getting into, i.e. supporting you a lot.
Georwian and others from this community will likely weigh in with more precise advise. But again, on first blush, the attorney's advice doesn't sound bad.
