In the money section of documents required under student visa, of course I plan on giving my bank statements from both my checking and savings accounts. My parents as well will help pay for the cost and I'll include statements from their account, my birth cert. for proof I'm related to them, and a note from them stating that I have permission to use their money. My boyfriend too is more than willing to help with costs of tuition, living expenses, and transportation.
For a student visa, you need to be able to show that you have a very specific amount of money available to you:
You need to have access to the first year of your tuition fees (approximately £12,000, depending on the course - your Certificate of Sponsorship from the university will detail what tuition fee you will need) PLUS a minimum of £7,200 if you will be living in London or £5,400 if you will be living outside London.
If this money will be coming from your own funds, all of it will need to have been in your bank account for a minimum of 28 days before you apply. If it is in your parents' account, as you have said, you will need to prove you are related to them and have their permission to use the money.
If you will be using loans, you need an official letter from the loan company stating the amount and date it will be disbursed to you (and you have to make sure that the UK school is approved to receive US loans).
My question is: should I include his bank statements and a note from him stating our current situation and how he plans to help support me by covering some tuition costs, living and travel expenses? I'll also be living with him in his house during my studies, so should I also include his mortgage statements for proof of accomodation?
I don't think you will be able to use any of your boyfriend's money to meet the visa requirements because he is not your parent or legal guardian, so I doubt there's much point in including his bank statements.
Even if you will be living with him and not paying much in living costs, you still need to show you have the required minimum living expenses of either £7,200 or £5,400 in order to get the visa.
The Tier visas are very specific - if you don't include meet the requirements exactly and/or don't provide the exact documents required, it will be refused.
Also, I realize I'm a "low risk" applicant and I'm just clarifying- in the money section and the acceptance of studies section, I don't need to provide all documents but I must make note on the application that I meet the requirements and I hold the necessary documents, right? Which also brings me to the other question... should I just go ahead and include the BF's documents in the application, despite being low risk?
You need to be able to prove that you meet the requirements if asked for the documents, but you do not have to actually include the documents in your application.
You must have access to the full amount of money required for the visa (or have an approved loan) before you apply though in case they do ask you to show evidence of it.
