Right, now I get it. I guess in this case it makes more sense to extend the visa exemption rather than exiting/re-entering, as I'm not planning to stay over 60 days anyway. Thanks very much for clarifying!
Thanks a lot everyone! And sorry for confusion but I'm Slovak so I should be allowed to enter without visa. And yes I'm applying for e-visa, but leaving and re-entering is what I was hoping to avoid, so do you know if there's any other way to extend my stay once I'm there? Or will I just have to leave within 45 days?
