Alison Atkin from Cambodia ... the embassy in Phnom Penh .. you will see a few guys at the door there to “help” in exchange of a few more $ ... I used their service .. it’s easier.. I noticed that when I tried to do it by myself they were asking more documents... I always had what they asked but I had to go back to an Internet cafe to print them etc.... so it was a bit annoying .
Now that was what I did.
Maybe there is an easier and faster way that I am not aware of.. we will see the other answers.
I entered Thailand with a tourism visa I obtained from the Thai embassy in Cambodia.
That gave us roughly 3 months (2 months + 1 month extension) to prepare all the documents.
First I registered the kids at their school.
The school gave me, after I requested, all documents I need to request a change from tourism visa to ED visa for my kids at the immigration division 1 in Bangkok (must be done 15 days before the tourism visa expire).
After that, I took a copy of the passports of my kids, plus again the papers from the school plus a birth certificate of one of the kid (no need all the kids) and I went back to Cambodia to request that guardian visa.
They normally ask a bank account with 10.000 us$ on it... you can easily open a bank account in Cambodia but that’s another subject.
I could get the visa without those 10k because my bank statement was showing regular transfers from overseas (they just want to make sure that you can provide for your family)
They gave me a cinglé entry non-o visa valid for 3 months.
At the end of the 3 months you extend it from the immigration bureau with a bank statement (THAI this time) showing at least 500.000 Bahts of transactions during the past 3 months.
I say it again .. I am not a professional on Facebook so I am not sure... i don’t mind sharing informations with the “group”.. bit as my answer would include details about my personal life, I would rather not those details to be seen by the entire world... if you see what I mean.
But ok.. i will answer anyway as I rarely see infos on the Guardian visa here... not there since long though...
Plus I am French so please pardon my very poor English .
