A few questions:
- Why California? (The UC’s are very expensive for out-of-state and international students, so, while a CA community college may give you a good transfer path to a UC, is that something you’ll be able to afford?)
- And related to the above: do you have enough money for two expensive years, if you save money on the first two years?
Some other states’ public U’s are much more affordable than CA’s. U of Arizona and Ohio State both have top astrophysics programs.
If you do want to be in California, look into Cal State Northridge, which (unlike most CSU’s) has an astrophysics major that claims to feed into top grad programs: https://www.csun.edu/science-mathematics/physics-astronomy For maximum affordability within California, you could transfer from a cc to Northridge and it would be far more affordable than a UC. Or perhaps you could afford to apply to CSUN directly.
You will find that there are few if any community colleges that offer upper-division coursework in any subject; their purpose is mainly to get your general education and lower-division courses done before transferring. If you’re hoping to transfer to a top UC or competitive private university, then a CC with an honors program would be ideal. Also look for programs and services specifically for international students.
One example: Cabrillo College.
They have an intl students’ program: https://www.cabrillo.edu/services/international/
They have both a planetarium and an observatory, which is quite unusual in a cc: https://www.cabrillo.edu/academics/astronomy/ (I realize astronomy is not astrophysics, but for community college this is probably as good as it gets)
They have an honors program: https://www.cabrillo.edu/services/honors/
And they are not far from UC Santa Cruz, where you could augment the course offerings by taking open enrollment courses in the summer. Transferring to UCSC would be very straightforward, and they are very strong in the sciences. As you can see on the Honors page, there are also transfer paths to UCLA and to private U’s. But again, the question will be whether you can get the financial aid you need. (More likely at private U’s than at UC’s)
On the other hand, maybe look into community colleges in Arizona? It’s much more affordable to live there, and their public university system has astrophysics at all levels of competitiveness. If you can transfer into U of Arizona, it has a top program. As you mentioned ASU has the major too. And Northern Arizona U, which is a really nice school but even less competitive than ASU, also has a physics+astronomy department.
For example, in Tucson, the beautiful and affordable city where U of Arizona is, there is this cc:
https://www.pima.edu/new-students/international/index.html
https://www.pima.edu/programs-courses/honors/index.html
They have the same basic courses in physics and astronomy as the CA cc’s.
From there you could have a clear transfer path into the AZ public U’s, and also apply to private U’s (no particular advantage between one state’s cc’s and another in that regard).
Likewise, you could look at Ohio, where OSU has a top astrophysics program but there’s also OU, U of Toledo, U of Cincinnati, and Miami U of Ohio - you could transfer to any of these from an in-state cc.
There are some great schools in California, for sure. But if you determine that the 4-year U’s in CA aren’t going to be affordable for you, then it doesn’t really make sense to do community college here vs in a state where you could afford the flagship or other state U’s. Choose the state with the best in-state options (both for program quality and for affordability), as you can apply to private u’s from anywhere but at least you’ll have a good in-state CC-to-4-year pipeline plan as a default.
Hope that helps…
P.S. Also agree with @Mom2aphysicsgeek that UA Hunstville would be a fantastic choice if you qualify for automatic merit. Huntsville is a hub of the aerospace industry, so aerospace engineering and all of the related sciences are very strong there… and the merit aid is an unbeatable financial deal if you have the stats. Don’t even bother with community college if you can get the big merit $$ at UAH or another automatic merit school.
