Community colleges don’t have financial aid for international students and most don’t have housing. However if you don’t go through Igcse 's they’re the only way you can study at a university. Igcse 's would be much less expensive though.
When I mentioned your uncle, I didn’t mean as a petition for you to immigrate. Students aren’t immigrants. They go to learn, not work and stay. In fact I’d you say you want to live and work in the us your visa will automatically be denied. So, your uncle’s help wouldn’t be with an immigration petition. It’d be help with logistics : would your uncle provide you with free housing and food while you study? Get you a car? It still means community college would cost you about $12,000…
Yeah, no one in their right mind would study in Yemen while it’s being bombed to ruins even if they can ‘pay to pass’ (note to readers: in many countries, including Yemen, teachers aren’t paid a living wage, their way of living depends on students paying them for grades.)
