And hopefully the witchhunt is over now, but have to follow the rules.

The border bounce, the second 30 day stamp for this calendar year (2019) will be no problem.

If you fancy another location there are flight to KL from Chiang Mai.

requirements are the same. she should cancel the wp and void the extension before she go out. She could go to Cambodian border at Ban Laem or Ban Pakkard to get a 30 day entry stamp or do a trip to Savannakhet. Agency like us or others can assist.

same, easy. Suggest Kanchanaburi n the two border in Chantaburi, namely Ban Laem and Ban Pakkard.

4 should be a problem, but as said, keep your finger crossed.

from 06 to 09:30 they are busy with mostly border runner from Laos and Vietnam, after that no problem, if you turn up yourself they will direct you to a small hut in front of Immigration, pay THB960 and they do all the paperwork, after that they will take you in a van to Myanmar side to stamp in/out, than back to Thai Immigration. If you have a valid Thai Visa, just make sure you double check the visa number and entry stamp.

No, this is no a requirement.

Limit is TWO 30 day border in one Calendar Year, so if you did one in Jan and one in Feb it is a NO GO, otherwise you should be fine unless you have a not cancelled work permit or an extension of stay based on study, that you should cancel before you go out.

I open the topic again, while we covered that this is not really visa related but travel related I wonder how your friend from Laos, BTW you did not specify Vientiane or Savannakhet, will travel internationally to Phuket to enter Thailand via Phuket International Airport. Once I have the answer I will close comment again, thank you for understanding. I know you could fly Vientiane to BKK and onward to Phuket by Air Asia, but that would be a strange travel pattern.
