he has a short weekend trip planned to Taiwan and then return to Thailand -- to avoid cancelling his visa, i told him he must obtain a re-entry permit before departing. was my advice correct?

TLDR : Answer Summary
A friend with a single-entry NON-IMM B visa intends to travel to Taiwan and must secure a re-entry permit before his trip to avoid canceling his visa. He seeks confirmation on this requirement. Comments suggest verifying whether it's a visa or an extension; if it's a visa and the entry stamp shows it has not been used, he may travel without a re-entry permit.
