How much should I let dating potential influence where I live?

I grew up in (foreign) country A but then moved back to my home country (B) with my parents. I plan to move back to country A eventually because I feel 100% at home in the culture there, but am just a bit unsure about the timing. The problem is that I'd like to get into dating (I'm 21) and country A has a really low amount of people of my type, whereas the country I'm originally from (B) has plenty (but I only feel 70-80% at home here). So I'm thinking I might postpone my move back to country A where this won't really be possible until in a couple of years when I'm more happy to settle down. I wanted to ask you older folks if you think this is a wise idea.
