Can I still use my UK student visa in my old passport, if the?
You can use it for entering the UK, you simply bring your old and new passports with you when you pass through immigration. But, as the passport is no longer valid, it cant be used for verifying your right to work by employers or for landlords to rent you a property. If you had a biometric residence permit, that can be used both for entering the UK and for proof of right to work and residence, even after you change your passport. You may get it transferred, but the cost (like the costs for most things by UKVI) is rather high. Once you are in the UK it may be easier and ever so slightly cheaper to apply for a BRP. Transfer your visa from your passport
