I live in Australia with my Thai wife(married in Australia)
I have lived in Thailand on a Non O retirement and have moved back to Australia for a few years
I have previously had a Non O marriage(3 months) granted by the Sydney consulate but as I live in Brisbane Queensland this year have used the new Evisa portal with Canberra embassy as the granting Authority
I like getting Non O over visa exempt as I have bank accounts and property in Thailand and need to change or update them On visits
I applied on the new Evisa portal and found that all I needed was a pdf or Jpeg of my Passport(which once uploaded fills in the personal data), proof of address(my superannuation statement), marriage certificate(Brisbane registry), proof of funds(my Australian share portfolio showing over the equivalent of 400k THB) my wife's ID card and a photo of myself.
I filled in the online form listing my flights already booked
It was very easy and not particularly detailed
I then submitted it where it sat in document check status for 7 days, then pending approval for another 7 days
Then approved at 2 weeks
Where I was sent a email containing a pdf of the visa grant which is in English except for the remarks line which states in Thai : "Thai spouse"
