We have freinds from California who want to come to phuket and have been told that they can only enter for 2 weeks then they need to leave the country and renter for another 2 weeks .
Has anyone heard of that as seems very strange to me.
TLDR : Answer Summary
There seems to be confusion regarding the length of stay for US citizens in Thailand. US citizens can enter Thailand under the visa exemption rule, allowing a stay of 30 days. Some commenters noted that if they enter by land, the previous rules for 15-day stays have been updated, and currently, they can obtain a 30-day visa on arrival. Miscommunication regarding the need to leave and re-enter after two weeks appears unfounded.
