I know that I can, until December 31, still fill it at the border (paper), instead of online. But I would rather save time if possible.

Please make sure that the agency is reliable, as 80%+ are simply gonna take your money and run. Most agents are fake agents, they do not exist. 6 times a year or 20 times a year doesn't matter. With your history you might get denied, up to the officer. They are especially harsh at Bangkok. My advice is to contact an agent and get Safe Entry / VIP. For 4k baht, the agent will get you into priority line for quick passage, no question asked, at the airport.

You don't need to tell them anything.

I have never filled TM30 quickly. Went I go for extension, I just do it there.

So it depend on immigration office. Khon Kaen & Udon Thani, they do not care. But to answer your question, ofc, it's not gonna be a problem to do it Monday.

Alan, unless you are over 50, don't do it. It's too complicated to stay long term.

Your son cannot legally be deported for overstaying until he's much older. He can overstay from 4 years old to almost 15 with 0 consequences.

I already got denied in December last year (Nong Khai), and got in with an agent at BKK. I plan to use Thai Visa Center this time around. They guaranteed 100% entry. I plan to do Non O based on marriage after that. I'm tired of border run.

Thank you! That's what I thought, but I went through search history here and found a few posts of people saying that it needed to be transfer although it was confusing between visa, visa exempt, or what.

I meant this: "So what I got told: "Give both passports to the guy at the passport control Booth when you stamp out they will stamp you out on the new passport and make a note that you entered on the old one and then you use the new passport to enter Lao". So I'm not bouncing that border.

@Pete ******

I have never heard of someone getting denied VOA in Laos :)
