On March 5th, you received this response from @DadTwoGirls: It is entirely possible that you might get accepted to some of these schools and find that you cannot afford to attend.[/quote]That appears to be what has happened.
Now, you are looking for funding. As an international student, who needs a full ride, you appear to be stuck.
On your student visa, your ability to work in the US is very limited in hours and funding.
Non-resident students on a visa typically work 10-20 hours at a minimum wage job. It’s money for incidentals and doesn’t even begin to cover tuition.
Further, no company in the US is going to pay you over $50K, in one year, without a degree, nor permission to fully work in the US.
The best funding comes from the schools themselves which is why research for international funding is crucial for someone who can’t afford the tuition and fees… If your current schools have already denied funding to you, you’re stuck. You can reapply to different schools next year and make sure you look at international funding.
