Hi all, has anyone with DTV visa has experience with entering and leaving Thailand and then entering again?

If I get DTV visa I'm going to visit Thailand twice during short time and it is not clear what immigration officers can asked in airport.

Lately, both entering and leaving Thailand have been chaos. There have been endless lines. Note—this is also pre-Songkran.

Upon leaving 2 weeks ago. I noticed the e-passport line. No human intervention. You can just enter your passport and photo taken, and the gate opens. You exit Thailand. When I entered, I got the usual 30-day visa stamp. Now, I have exited with no departure stamp. Will this be an issue when I go back to Bangkok in 2 weeks?

Does anyone know how much notice is needed to apply for entry and exit to Phuket before the travel date?

I've lost my departure card, because the new one is so much smaller then the old one and seems to have slipped out of my passport. How do I do when leaving the country next time?

I live in Nonthaburi and have multiple entries.

Dual passport question. One passport allows me:

1- 90 days on the visa exemption(Brazil).

2-The second allows me 30 days on the same visa exemption(Portugal).

Applying for a SETV on the Portuguese: 60days+ 30 (extension 1900 bath), leaving by land to Cambodia​, Phnom Penh returning by air with passport 1- 90 days + 30 (extension 1900 bath). Is there anything missing?
