Will my family face issues entering Thailand separately through different cities?

Hi All,

With the help from the school and from the members of the group here, i was able to get to the family and I our first "O" visa (we got it in our country and it is valid for 90 days). Now, I have a situation here. I understand that once we enter Thailand, we will need to apply for the correct visa (ED for the kids and guardian for us, parents). Thing is that my wife will enter Thailand first with the kids and I will only enter later, around 2 weeks after their arrival. Is this a problem? Another thing is, we will live in Chiang Mai, but wife will enter first in Phuket, as she have family there. Can we have any kind of problems for entering separated and through different city? I dont think we can, but trying to clarify as much as possible.

Thanks again
