It depends on what you're looking for. If you just want to chat a little, it is probably fairly easy, depending on the language you want. If you are looking for more serious study, you will probably do better with a community tutor or teacher because many people don't have a lot of time for more serious partnering due to outside commitments like work and family.

I haven't been lucky enough to find a language partner here.

Lifelong search, people come and go depending on how busy they are.

I think in two minutes. We can find our language patner.

In my opinion, you'd better ask "How long" instead of how much time. Well, it's not take much time to do that!!
