perfect, thanks for the confirmation.
Her O visa says...
Travel: Multiple
Visa Conditions: - (blank)
Date of Grant: 23 Dec 21
Visa must be used by: 22 Dec 22
Length of Stay in Thailand: 90 days.
Does this combination of Multiple entry and validity period mean that she would be stamped in for 90 days each time she enters from now until 22 Dec 2022? Assuming her health insurance covers the 90 days on each entry.
