I’m new to the group and looking for some advice.

I may have dropped a clanger even in the extensive maybe frenzied research with AI but any constructive advice is greatly appreciated. 

I have been speaking with a visa agent but this part seems vague. 

Arriving 17 October. I'll be on a Non-Immigrant O (retirement) and applying for the one-year extension here using the 800,000 baht method.

My son is 15 and travelling on a 60-day tourist visa. The plan is to extend him 30 days, then convert him to a dependent Non-O and get his own one-year extension once mine is stamped.

Has anyone done this in Hua Hin?

 • How did the timing work, given my extension has to be granted before his application can go in?

roughly what did it cost?

 • Anything you'd do differently?

Flights and visas are booked, so I'm looking for how to make this route work rather than alternatives.

Grateful for anyone who's actually been through it.

Thanks in Advance.

Unusual for the son's tourist visa to be issued so early. They normally don't send them out until a few days before you travel.

Phil Wilson I was also surprised. It came overnight from the day of application.

Will your son be going to school? If so an ED visa might be more appropriate. I'm not sure he'd be able to get a dependant visa

@Graeme ********

then he can't get an ED visa, like I said he may not be able to get a dependant visa inside Thailand either as you are on a Non-O

Just to clarify, you applied for a visa for your son in advance via the embsssy (e-visa) and you don’t mean visa exempt, correct?

BreezyGiraffe4639 - yes it does, visa exempt changes from 60 days to 30 days on Sept 15th. Some people are not aware of that. He says his son has sixty days with his visa. Since many people often mistakenly call visa exempt a visa, making sure he isn’t assuming his son can still automatically get 60

Days that way

I THINK in Hua Hin you can get your extension when you have 45 days or less left on your initial arrival stamp. That means you would be able to apply for a dependent visa after that. But you also need to have your 800,000 in the bank for at least 2 months when you apply for your extension, so it might be tight (usually to do a conversion from tourist to non-O, you need to have at least 14-21 days left when you apply).

Cost to do it yourself is going to be 2000 baht for the conversion, and 1900 baht for an extension. That's the same for all visas and extensions from immigration in Thailand. Your extension will also be 1900 baht paid directly to immigration.

If using an agent, the 14-21 day thing probably doesn't apply.
