Regarding the student visa.
Last time they grant me up to F6+ but I change school. What a waste.
How many years? Depends on the school's CAS letter. There are some differences between schools.
Regarding Debit Card
I applied the accounts and debit card in HSBC UK.
Actually, there are two accounts (one for savings and one for debit card).
Must applied with parent. Any HSBC in UK can do.
