Biostats and Bioinformatics have way better professional prospects than biology. At Carleton you’re admitted to the whole college so if you decide to switch&study Physics with an Art History minor it’s entirely up to you. However Engineering is off the table if you go there.
Carleton is a powerhouse in preparing students for graduate school, in particular science PHDs.
The 1st few posts in that discussion would be very relevant to you.
So, you have to decide what you prefer Engineering or Bioinformatics? The curriculum is very different, the environment and the types of internships (or careers) also.
Email UCI to ask whether a student in BME premed can switch to the ABET version before freshman registration (you want to make sure).
Note that mentioning a goal of working in the US or staying there during your visa intw is an automatic visa denial since your goal with a STUDENT visa should be to STUDY.
(Oncampus work is authorized, whether research or whatever. Off campus is absolutely forbidden and illegal, with serious consequences.)
Practical training comes in 2 forms:
CPT is off campus practical training, usually during the school year or summer. It can be part time.
OPT is 12 months after graduation, STEM OPT 27 months – MINUS ANY CPT.
(It “reloads” with each degree you get. It doesn’t mean a pathway to residency and citizenship like in most developed countries; the US does see it’s to everyone’s benefit to use the skills college graduates have learned but do not make the mistake to think there will be some kind of pathway. If you can’t find anything after college, you’ll have a few weeks, then you’re off.)
