I'm currently on H1B and it will expire in two years. I recently got married to a US Citizen and would like to file I-130 and I-485 concurrently. My question is do I need to file I-765 at all? If I need to file I-765, why? I still have plenty of time on my H1B. I'm not sure what the EAD from I-765 would give me more than my current H1B. Is it the benefit that I could switch job without H1B transfer with that EAD?
Please help me understand this role of I-765 in my case. Thanks in advance!
