I choose UCLA for you. In fact, It depends.
1. how old are you? girl or guy?
2. Where are you? If you go to UCLA, do you have to quit your current job?
3. If you have to quit your job to join any program and you have to considerate some clock-clicking thing such as to be married, you can think of UCSD so you can graduate in 2016.
4. At UCSD, Part-time and full-time share the same faculty and all the resources, including career service. I do not know UCLA.
5. I do not know whether it is the same extent to difficulty for you to get an internship at LA and at SD.
6. UCSD full-time is targeting at entrepreneurship.
7. I am in class of 2015. only 3-5(the youngest ones in our class) are in the finance sector for their internship in the summer. About 5-10 in marketing, strategy, supply chain. almost 50% of international students in my class. It's very very veeeery difficulty for those international student to get an internship. Generally, international students with CPA or CFA, accounting background can get some internship in small firms. Or, international students with Electronic Engineering or computer science can get a project manager internship in small firms.
8. If you do not need to quit your job to go to UCLA, I strongly recommend you to attend UCLA part-time program. You are going to have 3 more years of full-time working experience. It will be way easier to find a job at a boutique investment bank after your graduation. You can get more contacts via your work.
9. Do you kind of like your current job and working environment? Or you do not like, even you just hate your current working environment? if so, go back to look at "3,4,5"
