Do you need the original foreign wedding certificate and MFA stamped translation etc for a 2nd renewal of a yearly extension based on marriage? Having a nightmare - they might be ""lost". (Considering Immigration should have the documents on file from last year?)
TLDR : Answer Summary
For a second renewal of your yearly extension based on marriage in Thailand, you must provide the original foreign marriage certificate along with a certified translation and any additional documents requested by the local immigration office. It's important to verify specific requirements directly with the immigration office, as procedures may vary. Generally, each extension is considered a separate application, requiring full documentation.
