For Cambodia visa extensions, the timeline depends on the visa type and whether you use an agent or apply yourself. In practice, most foreigners use a visa agent because they handle documents and submission. Typical processing is: about 3–10 working days from submitting your passport to receiving it back.

Cambodia Visa Extension Processing Time (Start to Finish)

Realistic Timeline Breakdown

Day 1 — Submit documents

• Passport
• Photo
• Current visa information
• FPCS registration (commonly requested)
• Supporting documents depending on visa type (company documents, school letter, retirement proof, etc.)

Day 2–7 — Immigration processing

• Agent submits application
• Immigration reviews and processes extension

Day 7–10 — Passport returned

• New visa sticker/extension is placed in passport

Recommended Buffer Time

I recommend applying:

• Tourist visa: at least 7 days before expiry
• EB/ER/ES: at least 10–14 days before expiry

Avoid waiting until the last few days because delays can happen if:

• FPCS registration is missing
• Supporting documents are incomplete
• Immigration requests clarification

Example

If your E-class ordinary visa expires on 30 July:

• Submit extension: 15–20 July
• Processing: around 1 week
• Receive passport: around 22–30 July

For long-term residents, many people choose 6-month or 12-month extensions because they reduce the frequency of renewals. EB, ER, and ES extensions can generally be issued for 1, 3, 6, or 12 months depending on eligibility
