Any things to be careful of after getting GC?

I'm close to getting results for my 485. I don't want to already assume it's a pass, but I do want to be ready. Is there anything I should avoid or be cautious about after I get my GC? Basically, any restrictions that might cancel my GC or later citizenship application?

I just got my 485 approved. My lawyer told me that I should keep working in the same field, make sure service center jurisdiction is same, don't have criminal record, and I did EB1B so I need to stay with my employer for a while too. I'm sure you'll get positive results. Good luck!

I also heard that one should not be outside the US for too long. Does anyone know how long exactly?
