Congratulations for everything you’ve accomplished so far. Moving to a new country is not easy at all, especially during high school. You have done well, despite these challenges.
You will be treated as an international student, not domestic (unless there are public schools in Texas that will count you as a resident. I don’t know).
Affordability will be your main challenge, so you probably need to focus on in-state options that will be within budget. OOS schools will be expensive. Private schools can cost as much as $85k a year.
There are many knowledgeable posters here who can suggest appropriate schools.
