Equality between wives living in different countries

Q: Presently I have two wives. I married with my first wife while I was studying in Turkey and she got official status of my wife in the online government system in Turkey. I have married again a couple months back. Now I got a job in Turkey, where I can take my first wife only (since she is registered there and two wives are not allowed in Turkey) and cannot take my second wife due to the given reason. I am confused as to what to do?

If I take my first wife only and visit Pakistan in the holidays or call her on a tourist visa off and on, will this be fine and justified? Please advise me as to what I should do so that I may not become sinful?
