I have decided to leave the UK to apply for student visa. I am wondering if I can use a VFS service in a country that I am not a citizen of. I am thinking to go to Thai on a 60day visit visa and while I am there I will give biometric at their VFS centre. Would that work?

I am currently on my PSW graduate visa. My visa ends August 9 and I want to study a course starting in September 15 (estimate). So it is obviously more than 28 days that they stated. What I understand is that my course have to star within 28 day of my visa expire. what should I do? would I be reject...
