My daughter attended 2 UC’s (UG and Grad) as a resident student and made lots of friends with non-residents. It’s not the first thing that is asked.
How will students know that your son is from OOS unless he tells them or wears a shirt that says, “I’m not from California”. It’s not an issue. There are hundreds of students from everywhere on the planet at the UC’s. (Non-resident students bring in the cash for the State.)
Also, people don’t realize that California kids come from a variety of locales: Large agricultural farms up and down the state. Lots of coastal and wooded areas. Desert communities and cities. (Our daughter’s school was over 500+ miles from our home). The majority of the State is not “beach party” central-SoCal is really small in comparison to the rest of the state.
The students blend in and no one really cares where anyone is from unless they want to plan a visit out of state. (Remember, that this is California and, generally, very welcoming and social.)
Please be aware that most of these schools are HUGE universities. The freshman and sophomore classes are large. At some universities, there are weeder-type classes. Some freshman math classes have several hundred students.
Merit dollars are few and minimal because, remember, that the State of California taxpayers pay the bills. Assume $2K-$5k for any scholarships per year. That barely covers the health insurance fees. Are you willing to spend over a quarter of a million dollars for a public school education in California?
Most California residents receive some form of financial aid from Cal Grants, blue/gold scholarships, university grants. As a non-resident, your son will not qualify for that funding.
If you think that only wealthy students attend the UC’s, you are mistaken. Every financial level is there.
No, absolutely not and it’s important to note that too many parents listen to their children and put their homes up as collateral, to get loans, to pay for the UC’s. That’s financially risky and irresponsible. Parents have a budget. Anything over that leads to ridiculous loan repayments.
