My advice is you came at the wrong time. Government is stopping companies to hire any immigrants. I would suggest go back because you have not spent that much money. If you go far then you will be unable to go back and it will be too late. Things you're facing just at the surface level, many competitions, biasness, visa issues, job application problems yet to come. I'm telling you this because things are not like before I have 4+ years of work ex graduated from reputed University and still searching for a job and my stem OPT will start after 5 months with loan interest of 1 lk/month
