Two years ago I had applied for Portuguese citizenship (As my father is a Portuguese citizen by descent) while I was in Goa. Then I traveled to the UAE with a visa on my Indian passport. After being in the UAE for a couple of months, I received a letter from Portugal with my Portuguese birth certificate. So, being in the UAE, I applied for my Cartao de Cidadao, and now will be appearing for an appointment to apply for Portuguese citizenship.
My family resides in the United Kingdom and I wish to join them there. My visa here in the UAE on my Indian passport expires in a few months and I am planning to cancel it and directly go to the UK showing my Portuguese passport at the airport.
Is it possible to travel to the UK from the UAE, if I show my Portuguese passport at the airport exit and not surrender my Indian passport? I plan to surrender it in UK. Any guidance will be highly appreciated.
