Ask an Immigration Solicitor. Get an Answer ASAP.
Good morning, if your withdrawing a leave to remain application you should contact the home office beforehand because if a decision is reached they will not give you back the application fees. I will send you details to contact home office.
When you withdraw application they would refund to the account you made application. You would have to leave before receiving refund as it can impact you applying for tourist visa again if you become an overstayer.
Glad to be of assistance today. Have a great day!!
