Say that my EB1-OR application petitioned by my university department is approved and my I-485 has been pending for 180 days. I now get a great job offer from a company as a Senior Scientist in their R&D department. The work is basically the same as in the university byt the pay is 2x. Can I take the job offer without interupting the I-485 process, or do I have to start from scratch again?
