Complex passport expiry question from a Sri Lankan in UK
I am a Sri Lankan citizen living in the UK under the HSMP visa sheme. I just realised my passport expires on the 21st of December. My UK visa expires on the 25th of November(HSMP/Tier 1 general). I checked with the Sri lanka embassy in the UK regards to my situation and they said that it takes 8 to 12 weeks to process my passport application(in order to get a new passport) so I thought that If i travell to sri lanka in the first week of November just for a week to get a new passport will this cause problems at either immigration officers at arrivals and departures specially in the UK? because o my return i will have only around two weeks left before my visa expires? and also when they issue a new passport they cancell my existing passport does that mean my visa will not be valid? Please let me know I would be extremely greatful. thanks a lot..
