I now have dual citizenship, and I live in my 'new' country. I don't really want to obtain and maintain two passports, with the associated admin and costs.
If I continue to travel on my 'old country' passport, and in due course renew it, can I let my previous 'new-country' visas in my old passport expire (ie not renew/transfer them into the renewed passport) and rely instead on my 'new' citizenship certificate to allow entry into my new home country?
I realise the exact rules may differ by country, and I will check them out in my specific case, but before I do: does anyone have experience of this for their own countries?
