As I told the Uni EAP rep: who in their right mind would automatically assume that the NHS of a first world country would NOT be considered as equivalent to our rather pathetic Medicaid system (which is grounds for exclusion)?
The problem might be that not all first world countries offer their national health service to foreign students to use for free/flat fee and that health insurance from their own country would be needed.
http://www.topuniversities.com/student-info/student-finance/how-much-does-it-cost-study-germanyThe home university would have to know how each country with a national health service worked and keep up to date with all changes these countries make to who can use their NHS for free, or they might leave their students without any health cover abroad. The UK changed their NHS rules this year and in 2010 for EU students. Even in the UK, the four countries that make up the UK have their own rules for their own NHS.
Not trying to stick up for the university, but leaving a student with thousands of $ of medicals bills in another country could leave them open to be sued.
Can you get the university in Scotland to provide her with a letter to confirm that Scotland will pay for any medical treatment she might need while on her visa?
Other things to think about might be:-
What would happen if she needed to be airlifted home with medical staff in attendance for the journey? Would you have private insurance to cover that if you don't use the university insurance?
Will NHS Scotland agree to pay all her health bills if she travels out of Scotland to say England and has an accident there and needs treatment? As said, with a visa of over 6 months she would be covered for that under the IHS scheme but without that England will bill her.
