Can I submit my Non-O retirement visa extension application on Monday if my visa expires on a Saturday when Immigration is closed?

If your Non-O retirement visa expires on a Saturday when Immigration is closed, it is advisable to submit your extension application before the expiration date to avoid complications such as overstaying. While some immigration offices may allow submissions up to 45 days prior to expiration, waiting until the last moment can lead to issues, especially if additional documents are required. It is suggested to obtain necessary documents, like a bank statement, as early as possible to ensure a smooth application process.
