We lived in the UK for 2 years and then, returned to our country before our student and dependent visas expired. Before coming back, we surrendered our NHS registrations. However, the bank accounts we opened while we were there, were a grey area for us. We had a good credit repute going so we still operate those accounts although we are no more in the UK.
Is that officially allowed? This is important especially since I wish to submit my UK bank statements when I apply for visas.
