Job Change with GC, wife application pending

[485_spouse]

I filled my GC via company in 2002, employed with them since 2000. I got mine in last year GC flood.
I am working at the client site for last 4 years and they are offering a job.
6 months have passed since I got my GC.
Since my wife's application is still pending, is It OK to change jobs?

Any thing I should be aware of before making this change?

Thanks in advance
