I have two passports - South African and British. I am leaving SA for the UK on 6 May.

I have to leave SA on my SA passport. Am I going to get stopped at the airport for not having a visa?
Before the new visa rules, it wouldn't have been an issue but now I am a little concerned they wont let me fly out of SA.

Thanks! Appreciate the help. Will call VFS now...

You are supposed to have a letter, but to be honest its hardly worthwhile. The only time you will ever be asked for it is if you are staying in the UK and your SA passport expires and you try and get a new one from the UK. They then ask you for your "dual citizenship" letter. If you dont have one the SA passport office in London will then sort one out. What for I dont know as you will never use it again!
The UK authorities dont require it. As long as you leave and enter SA on your SA passport and Leave and enter the UK on your British passport then you will never have a problem. In fact when we go back to SA we just use our British passports nowadays. Just dont use your SA passports coming in to the UK.

I have lost my letter from the as home office giving me dual passport approval, how can I get a replacement letter? My as passport has expired & I have to renew this using my dual passport approval letter which I have lost!

I am going back to SA on Holiday mid June and have dual Citizenship for SA & Australia. My problem is I'm still awaiting my renewed SA passport, which I applied for 9 months ago, and not getting much joy with my enquiries. My query is will I be able to use my Australian passport for the whole trip if I don't receive the Sa passport in time?

I am going to the UK and awaiting date confirmations,i have dual passports but it may be that on my return date of my SA passport expires, What can i do to ensure that when reentry in SA i have no hassles .

I am currently living in the Uk and have both SA passport (Expired) & Irish. I went to renew my passport a few weeks ago, but because I did not have the dual citizenship letter - I have lost my SA citizenship & they took my passport & ID book away from me - said they will send it to me within 2 weeks, but it will be invalid - still waiting!!! Don't take the chance!!!

I've been granted British citizenship this year through aturalisation and I did not apply for retention of SA citizenship. According to the home office website I've automatically lost my SA citizenship. Does this mean I can travel on my British passport without any issues?

Can someone please offer me advice about which passport to use when checking in? I have dual nationality S.Africa/U.K. I believe from reading other posts that it is better lo leave SA on S.A passport & enter U.K on British passport but what about at check in? The first post also applies to me too. If I leave on S.A passport wont the officials ask where is my visa to enter the U.K? Do I then just say that I have a British passport as well??
Any advice would be much appreciated.

I also have both a SA & UK passport but never applied for a Dual Nationallity Letter. I have travelled to and from the UK since obtaining both passports and have never been asked for anything else apart from both passports when leaving SA. You must enter the UK on your UK passport otherwise you need a VISA. When leaving SA do so on a SA Passport but make sure you have your UK passport at hand as SA immigration, at the airport, will ask to see it to verify you dont need a VISA for UK entry. I beleive the letter of Dual Citizenship is only required if you allow your SA passort to elapse while in the UK.
