You can do quests in another country even not your own except for missions.
For example I am from sandoria- i can only do sandorian missions, but i can do quests from jueno, sandoria, windurst, selbina, mhura, and bastok.

But if you decide you dont like your country just get 10k and move to the country of you choice.
However, I not who to talk to.

I moved from windurst to sandoria as soon as I started the game.
I have my windurst conquest ring as well as a sandorian conquest ring.
i got my san ring due to that fact that when sandoria won recently, I paid 4 k conquest points to get it.
