Overview

An extension is a request for more permitted stay

A visa and permission to stay are different. Before your current stay expires, ask your institution and the relevant Immigration checkpoint which education extension process applies and how far in advance to prepare.

Check the stay-until date in your passport or entry record.

Ask the institution for its confirmation and extension-support letter early.

Use the official TM.7 form and education-specific evidence required by Immigration.

Do not confuse an extension request with a 90-day residence report.

Details

A careful extension workflow

Use your institution’s guidance for education paperwork and the local Immigration office for forms, timing, fees, and submission procedure.

1. Start with the expiry date

Plan backwards from the current permission-to-stay date, not from the visa sticker’s issue date.

  • Check your passport for the latest entry or extension stamp.
  • Ask Immigration when your category may submit an extension.
  • Contact the institution early enough for its paperwork process.

2. Assemble the application

The institution’s letter should support the actual course and requested period; Immigration may require additional official records.

  • Complete TM.7 using current instructions.
  • Bring originals and copies requested by the checkpoint.
  • Verify photo, fee, and any school or ministry forms locally.

3. Submit and keep proof

Follow the submission method and respond to any request from the officer or institution.

  • Attend the responsible Immigration checkpoint where required.
  • Keep the receipt and note any return or decision date.
  • Check the passport stamp before leaving the office.
