Baby from alien and alien

[bobnoise]

I live togheter with my farang wife and my son in Thailand since over 3 Years.

Me: Swiss Citizen, 39 Years old

my wife: Swiss Citizen, 38 Years old

my son: Swiss Citizen, 3 Years old, born in Thailand

In the last 2.5 Years I had my own business and also a work permit. I had 1 Year Non-B-Visa and also my wife get 1 Year visa, about my B-Visa.

But now i sold my busines and i loose my B-Visa. But we want to stay in Thailand. Today we stay here with Tourist-Visa.

It is possible that my son get the Thai Citizenship and we as parents get O-Visa? My son have a birth-Certificate from Thailand.

I find a list on this site: "Born within the Territory of the Kingdom of Thailand"

Point 11:

Legal Alien , Legal Alien, Register -> Thai.

What does this mean: "Legal Alien" and "Register" ?

My target is to get long term visa for Thailand. I dont want to work here anymore. With my money I can survive here many years and my wife get a small pension from switzerland (30000 per month)...but we are too young for get a retirement-visa.

Can somebody give me a recommendation? Thanks for any help in advance .
