What should I consider when taking my Thai wife to South Korea?

Traveling to South Korea with a Thai wife appears to generally go smoothly if traveling together. It is essential to have basic travel documentation, including passports, proof of relationship (like a marriage certificate), and a return ticket. Comments indicate that while traveling, officials may be cautious of solo Thai females, so clear identification of relationship status is advised. Previous experiences show that some travelers faced no inquiries, while others faced scrutiny, underscoring the importance of preparedness.
