Rebuilding?

I'm 38yrs M, recently legally relocated to the US, now here for 6 months.

On an F1-Visa, STEM course (MSc in AI) in a renown private university, and another aligned certificates in an Ivy league University.

​

I am targeting a solid $20,000 income per month:

1. Is it feasible?

2. What are the pathways of success in this country considering my position/options?

3. Any meaningful and/or relevant feedback from those who've been there, done that?
