Employment Based Green Cards

I'm from Bangladesh and am pursuing a non-thesis Master’s degree in Civil Engineering at Texas A&M University. My area of specialization is Geotechnical Engineering. I’ll graduate with my degree in May 2025 after completing a co-op with one of the top Engineering and construction companies in the United States. The company also offered me a full-time position after my graduation so that I could continue my work with them. Many PhD candidates from my country with a master's degree are applying for EB2-NIW using their citations and research experience.

1. Since I lack a prominent research background (basically, I have no experience at all in terms of publication/citation), do I have a chance of getting approval for EB2-NIW?

2. Is citation/research compulsory for EB2-NIW to get approved?

3. If I want to apply in the future, how should I prepare my profile to increase my chances? I’m more interested in working in the industry than in research and academia.

4. I want to mention that, from my experience, there is a huge demand for geotechnical engineers in the civil engineering industry, but not many people, especially Americans, are pursuing this major. Can I use this fact to show national interest?

Two general questions,

1. What are the benefits of filing an EB2 NIW for a person whose I-140 has already been approved by an employer in the same category apart from NIW, not depending on your employer? Also, can you get your I140 approved priority date to your NIW?

2. Is it possible to renew the H-1B visa stamp before expiration? For example, if my H1B expires on November 1st and I apply for a visa stamp in October with approved extension I797, Would I be able to renew it?

I started the self-NIW application while working with employer A, but for some reason, I could not file the petition. Later I got laid off from employer A and now I'm working with employer B.

I want to restart the NIW application. Questions:

1. Since I got laid off with employer A, will that be a challenge/red flag in my petition?

2. It's only been one month with employee B. Shall I wait some time at company B to restart my NIW application? or doesn't it matter?

Q1. I-485 Filed for EB3 ROW Category While I am not in PERM Sponsored Role

I am stuck in the scenario where my green card was prepared for a future/prospective role, but the AOS/485 is filed, and I still do not have that prospective role (not promoted yet). What are the issues or risks if the green card is approved but I am not holding that future/prospective role? Is it necessary for me to be in the PERM-sponsored role (future role) at the time when USCIS approves I-485?

If the green card is approved and I am not given that future sponsored role, what are the issues/consequences? And how do we go about navigating this process?

Q2. Filing of GC

If my green card application is prepared for a future role and I am not in the perm-sponsored role (future role), i.e., I haven’t got a promotion while the AOS is filed, is it necessary for me to have that future role or not? If yes, then at what stage will the promotion be required for me to get a green card? And if I don’t get a promotion by the time the green card is approved, will there be any issues? If yes, what are the issues?
