Advance Parole

If you have an EB-1A-based EAD and a pending I-485, starting an unrelated business (such as teaching) is risky. Your EB-1A petition asserts that you intend to work in your field of extraordinary ability. Shifting to an unrelated field could raise questions about your original intent and impact your green card application.

Additionally, traveling on Advance Parole in this situation may pose some risks. It’s advisable to either have a job offer or a clear plan to work in your field (such as consulting with clients) before traveling. Proceed with caution.
 

 You can stay in India for an extended period while your Form I-485 is pending, especially if you have a valid Advance Parole document and Employment Authorization Document (EAD) for five years. However, maintaining continuity in your job is crucial. If you're still working remotely for the same employer or a different one under the same or similar job, there shouldn't be significant issues.

Quitting your job may raise questions about your green card eligibility. However, if you obtain a job offer from another company, filing a supplement J to demonstrate job continuity is advisable. This ensures that you can re-enter the US smoothly using your Advance Parole upon green card approval.

You can return to India to work for the same employer for multiple years and then come back to the US. You can also convert your case to consular processing if needed, provided there's continuity in your job. As long as your Advance Parole is valid, there shouldn't be any significant impact on your pending Form I-485 until your priority dates become current.
