Is it normal to receive a non-imm B extension for 13 months from the One Stop Immigration Service in Thailand?

The user received a 13-month extension on their Non-Immigrant B visa, which is valid until December 12, 2023. They are concerned whether this duration is standard practice and if it could cause issues during the next renewal, particularly because it extends over a year. A comment suggests that typically, the duration of extensions reflects previous expiration dates, hinting that obtaining extensions beyond a year could be atypical.
