Can I apply and be admitted
to a UK college after
an American high school?
I have terrible grades.
Do they have such colleges
where they just admit everyone?
Prepare yourself for the fact that this wouldn’t work out. The problem for you would be the immigration part. To get a student visa, you need to meet certain requirements (basically, it’s Bachelor’s degree). Additionally, you will need a proof of your funding.
In the UK, funding is mostly reserved for local students. I suggest that you select some colleges and just ask the representatives if they can accept you and if you can apply.
In case if you have a dual citizenship, this problem disappears, but you haven’t mentioned that.
Of course, there are terrible colleges for the students with terrible grades. Pick a college and check their requirements on the website. After you are admitted, you need to get a visa.
For this, you have to prove that you are admitted and have sufficient funds for studying (tuition, housing, etc. because you are forbidden to work). Then, go to the UK to start your studies.
There always are low-quality universities that accept students with low grades. However, the education will be at a low level, too, and it will still be expensive because you’re a foreign student.
So you’d better improve your situation than choose a poor university.
UK colleges are very picky and expensive. For foreigners, the situation is even worse.
You have to get visa and money.
No, you cannot. To get a student visa, you need good grades. In the UK, they’re not accepting bad students just for money and degrading education like in the USA.
