I just got married with a British Citizen and in the process of applying a spouse visa, so the embassy hold my passport now (from before i got married). Now that I am married, I have a surname. Is it urgent for me to change my name in my passport? Which means making a new passport. If I dont change it, will it cause any problem for us in the UK? Such as dealing with anything require us as a married couple, spouse. Maybe mortgage or insurance..

If I make a new passport after my old passport stamped with my spouse visa, what will happen then? Will the visa be transfered or anything like that?
If I take my passport from the embassy, will it postponed our process to get me a spouse visa? Because its taking long enough as it is


Thanks a bunch
Really appreciate any infos
