An MBA a student who is in tier 4, can change to tier 1 entrepreneur if they have pound 50,000 available? Is it okay if that is personal money?

I want to confirm a rule

1) A person who is in tier 2 ict visa, can not go back to home and apply for tier 2 general right? Unless they serve a 12 months cooling off period?

Even if I go back to home country they introduced a 12 months cooling period for tier 2 ict to tier 2 general application. So, the door to UK is officially closed to any non eu person. Except for millionaires of course, as they can still apply as tier 1 entrepreneur for pound 200,000

Thank you! You mean he can leave UK with COS in hand and apply from outside right? No cooling off period or anything?

Also, if he decides to finish study, then can he switch to tier 2? Or he has to leave UK for that as well?

My brother is doing executive mba from a london college. He is in tier 4. The course is for 16 months, now after 4 months in the course he has got a great graduate level job offer, which will provide him COS.

Can he switch from tier 4 to tier 2 general now, without any problem?

Thank you very much for your kind help! I really appreciate it.

In UKBA site it is written that a person can switch from tier 2 ICT to tier 2 general if "Tier 2 (Intra company transfer: established staff), if you are applying to switch sponsor" NO mention of any date here. You can check it here- http://www.ukba.homeoffice.gov.uk/visas-immigration/worki...
