Can I get a re-entry stamp for my single entry non-immigrant O visa in Thailand?

The user inquired about the procedure for obtaining a re-entry permit for their non-immigrant O visa, which is valid until October 11th, indicating they plan to leave Thailand briefly but return within two weeks. The responses clarified that as long as the user returns before the visa expiry date, they can get a re-entry stamp at Bangkok airport or at an immigration office, where it's sometimes easier and might cost around 3800 Baht. They were also reminded of the option to apply for a visa extension ahead of time.
