Job Searching Amid Career Crisis (Corp development, sell side, or buy side choices) as foreigner in USA

Hi everyone, I encountered some career crisis recently.

I am an internal student graduate from an ivy school last year with MPA focus on economic and financial policy with minor in real estate.

The job mainly focuses on corporate finance in corporate debt, credit research, and issued ABS, some corporate development. But my boss told me she will not sponsor my visa because of RFE last month. So I am thinking about the exit opportunities.

My career is kind of atypical. I am wondering what should I choose more suitable for my career. I really want to move to selside investment bank or buyside private equity .

What are the best chance for me in terms of industry? Would a foreigner easier to break in? I listed those industry I would like to pursuit, What do you guys think about my chance based on my current and previous experience? Also in geography wise, should i move back to NYC instead of Dallas.
