Are physical A levels colleges for mature students still around?

I'm trying to look for A levels colleges that offer it to mature students and it seems like there are almost none.

The worse part is that I'm an international student which makes it even harder to secure a visa.

I know that there are Access courses, but I feel like A levels will open more doors.

I do not feel confident with self studying A levels, so I'm just here to ask if anyone knows of any colleges that take mature students for A's?

I feel like I'm cooked :(
