I hold an H1B Visa, and it is time for an extension. At the same time, I applied for my I-485 a few years ago, and I recently renewed my EAD, which is valid for 5 years. My priority date is June 2013. At this time, I am a bit confused about whether to move on to EAD or if I should continue to extend my H1B. If, for any reason, my H1B extension goes wrong, will I still be able to use my EAD? Thank you always for your support.
You should maintain your H-1B while your I-485 (AOS) is pending. If something goes wrong with your I-485, you could end up without legal status or work authorization, creating complications. Keeping your H-1B (or L-1) active provides a backup. While your spouse can use an EAD, losing their status is less risky than the primary applicant losing theirs.
