I will travel on holiday to several countries eventually using both passports of my dual citizenship. When I return to my home country and enter immigration, I will need to fill in an entry declaration form listing the countries I have been to during my trip.
The passport of my home country will only have stamps / visas from some of the countries I visited. On the declaration form, do I need to fill in all the countries from both passports, or just the ones visited using the passport of my home country?
