First off - it sounds like you’ve taken advantage of the opportunities at your school and are making a plan for college - you CAN make this happen. Step one is you need to understand a bit better about your parents’ financial situation. While many parents struggle to discuss these things, it’s imperative for you to have a better idea of the type of support colleges will offer. Many, many, many people qualify for financial aid and sometimes the more expensive schools are more generous with aid.
It’s impossible to develop a list of schools before really understanding the financial piece. Sit down with your parents and run a few net price calculators to get a general idea if you qualify for aid. You can start with extremes and run Oregon State and MIT. MIT is ultra-competitive and expensive, but it will let you know quickly what kind of aid a generous private school will offer.
Once you understand that piece, you can develop a list. I’d encourage you to think a bit about how set you are on nuclear engineering - it will limit your list by quite a bit.
I actually think the foreign language is the easiest piece. Yes colleges want it - but they also do understand small, rural schools have limited options. They are evaluating you in the context of what is offered at your school.
Best of luck to you!
