With little evidence of financial security, backing of friends and family, why'd you wanna moving to NYC of all places? You'll initially end up struggling to get a job. Yes, bigger city = more opportunities. But would you rather struggle to find a place/survive early-on or do it at a comfortable pace?

There are quite a few cheaper alternatives where money tends to go a long way. What you'd end up paying to rent a room in NYC will be more than sufficient to rent a one-bedroom condo in city like Omaha, Dallas, or Oklahoma City. You'll also rely very less on others if you moved to more affordable cities.

What did you major in? With a valid work authorization (your GC) and a Master's degree, you already have a massive upperhand.

Btw, I'd highly advise you to take driving lessons (if you haven't done so already). In bigger cities, taking classes prior to getting a license tends to be pricey.
