# Visa Extensions in Guangzhou
You came to Guangzhou for Phase 1 of the Canton Fair. You found an incredible factory, but they are located in Zhejiang province. You decide to change your flight and stay an extra 10 days to visit the factory.
Before you change your flight, you must look at the "Duration of Each Stay" (停留期) on your Chinese Visa.
> **💡 Withyou Trip Expert Verdict:**
> "Do not play games with Chinese Immigration. The penalty for overstaying your visa is **500 RMB ($70 USD) per day**, up to a maximum of 10,000 RMB ($1,400 USD). Worse than the fine, if you overstay by more than a few days, you will be detained, deported, and permanently banned from receiving a Chinese visa for up to 10 years. If you need to stay longer, you MUST apply for an extension 7 days before your visa expires."
## 1. The Visa Extension Matrix
| Visa Type | Can it be Extended? | Difficulty |
| :--- | :--- | :--- |
| **M Visa (Business)** | Yes (Requires new factory letter) | 🟡 Moderate. Must prove business need. |
| **L Visa (Tourist)** | Yes (Requires hotel/flight proof)| 🟢 Easy (for a standard 30-day extension). |
| **144-Hour Transit** | 🔴 NO | Impossible. You must leave the country. |
| **APEC Card** | N/A (Valid for 60-90 days) | Best option for frequent business travelers. |
## 2. Where to Apply: The PSB
You cannot extend your visa at the airport or at a police station.
* **The Location:** You must go to the **Guangzhou Public Security Bureau (PSB) Entry and Exit Administration** located at 155 Jiefang South Road (解放南路155号).
* **The Timeline:** By law, you must submit your extension application at least **7 days before your current visa expires**. If you walk in on the day your visa expires, they will likely deny the extension and order you to leave the country immediately.
* **The Reality:** The PSB will take your physical passport for up to 7 working days to process the extension. They will give you a yellow receipt. You cannot travel by high-speed train or check into a new hotel without your passport, so you will be stuck in Guangzhou during processing.
## 3. Required Documents for an M (Business) Extension
Immigration officers will not grant an extension just because you "want to look around more." You must prove a legitimate business need.
* **Valid Registration Form of Temporary Residence (境外人员住宿登记表):** You must get this paper from your hotel front desk.
* **A New Invitation Letter:** You must get a new, officially stamped letter from the Chinese factory you intend to visit, stating exactly why you need more time.
* **Your Company's Business License:** A copy of your home country business registration.
* **Proof of Funds/Flight:** An onward flight ticket proving you intend to leave after the extension.
## ❓ Frequently Asked Questions (FAQ)
**Q: Can I just take a train to Hong Kong to reset my visa?**
A: **Yes!** This is the most common "Visa Run" strategy. If you hold a multiple-entry Chinese visa (like the 10-year US/Canada visa), you can take the high-speed train from Guangzhou to Hong Kong, spend the afternoon eating dim sum, and cross back into mainland China the same day. Your "Duration of Stay" clock will automatically reset to Day 1 upon re-entry.
