Input: I'm an Indian citizen who will be starting my studies in France this autumn. So I will be having a French Long Stay Visa as a student. However, I am pursuing a mobility programme, which means I will be moving to the UK for my second semester.

Would it be possible for me to apply for my UK Student Visa (which I believe is a PBS/Tier4 visa) while in France? (It seems the CAS will be issued only three months prior to the start of course, which of course implies, that I will get it only after I'm in France.)

I had contacted the International enquiry office and all that I've been told is :

With regards to your query, you can apply for a visit, EEA or Tier 5 sportsperson or entertainer visa in any country in which UK Visas and Immigration accept visa applications. If you wish to apply for other PBS visas or a settlement visa, you can do so in your home country or in a country in which you normally live.

It is advisable to apply for a UK visa from the city where you are documented as a resident. Where an applicant wants to apply out of their region, they must provide a compelling reason as to why. Any acceptance to do so is up to the discretion of Home Office but, as an indication only, visitors (for example) can generally apply from any location. Please note that there might be delay in application if applicants apply from out of region.

PS: My duration of study in UK would be a full year, so I can't apply for a short-term visa.
