ben seninle olduktan sonra nerde yasadigim önemli degil türkiye letonya farketmez yeterki seninle olayim

Thanks

 It is not important where we live, Turkey or Latvia it doesn´t matter, It is enough I will be with you.

This is the general meaning. Wait for corrections though as I am only learning.

 since being with you it is not important where i live, turkey or latvia it does not matter , it´s enough just that i am with you

 oops I forgot the first bit  At least the rest of it seems right!

i wasn´t correcting i just posted slowly 

 no problem even if you were correcting. Any help is always appreciated.

What´s olduktan sonra ?

olduktan sonra = since (...tan/dan sonra = since)

olmak = to be

+duk = past tense for we

therefore meaning is since we have been

thanks Henry

´ben seninle olduktan sonra´

Does this not mean ´after I am with you´   (it doesn´t matter where .......etc)

Surely the suffix here is ´diktan sonra´ which gives the meaning ´after ....ing´

So in this case literally ´I after being with you´   ´after I am wth you´
