I'm travelling from country #1 to country #2. I have passports for both these countries.
I will be using the passport for country #2 on my way there and passport for country #1 when returning. On my way to country #2, I have a layover for 12 hours and wanted to get a visa to explore a bit.
Question is, is it possible to have a visa on my passport #1 even if I'm using my passport for country #2 that leg of the travel?
