Residency for Children

Just moved here with my wife and three kids from the US. We did not start our residency in the US because we wanted to "vacation" in the area for a year or so before we made the decision to become residents, and I really saw no benefit other than not having to pay exit fees.

After six months, which is I am told how long I have to wait before applying now that we are here, I plan on starting the residency process.

My question is:
Is there any reason, other then the overstay fine, for my kids to become residents at this point? Residency and cedulla for 5 people is not cheap. I am thinking of applying for residency for myself and my wife, and not applying for the kids until they are older (16ish). Is there any reason this would cause a problem.

Thanks,

Also,

I would like to apply for the expedited "investor visa" as a retiree. I am employed full time, working overseas on a rotational schedule. (gone a month, home a month). I have an employment contract, and receive regular paychecks. I meet the income requirement. The wording of the law says to me that I would need income from a 401k, retirement fund, rental income and such. Would I be able to apply for the expedited retiree visa with income from a job?

I met with a DR lawyer, and he told me that now that I was here I had to wait six months to apply. I fly back and forth every month, so it wouldn't be a big deal for me to start in the US either. I am just waiting until I know we are staying for sure.

That is the only issue I can think of, is the schools. And when they are older and start venturing out into the world and looking for trouble
