Can you renew a marriage visa early in Thailand and what is the time frame?

In Thailand, the ability to renew a marriage visa early depends on the immigration office, with some offices allowing renewal 30 days before expiration and others permitting 45 days. It's important to note that while you cannot technically renew a marriage visa, you can extend it if you meet the requirements. Additionally, some individuals have successfully extended their visas even two weeks before the expiration date, indicating a degree of flexibility depending on circumstances.
