OP said he’s a first gen immigrant (not relevant for college admissions), not first gen to college.
Agreed, OP has an impressive profile and is competitive for all his reaches.
@ceIebix, you haven’t mentioned your budget - that’san important consideration.
The only other thing I’ll add is that your best chances at most of your other reaches (not Caltech) are in the early round, but you’ll only be apply to one of these REA/ED. You may want to reconsider your application strategy. I don’t believe MIT provides you an advantage applying EA.
