**The Nature of Intermediary Accounts and How They Work**  

Intermediary accounts are bank accounts or financial institution accounts opened in neutral countries outside the scope of sanctions. These accounts act as a bridge between Iranian accounts and foreign transaction counterparts. Typically, these accounts are opened in countries such as Turkey, the United Arab Emirates, China, Armenia, Georgia, or some European countries with broader banking relations.

**Steps to Set Up and Use an Intermediary Account**  

1. **Selecting a Suitable Country:** The host country must meet the following criteria:  
  - Political and economic stability  
  - Extensive global banking relations  
  - Relatively simple account-opening procedures  
  - Limited compliance with U.S. sanctions  

2. **Registering a Local Company:** In many cases, you need to register a local company in the third country. This is typically done through:  
  - Hiring a local lawyer  
  - Submitting identity documents  
  - Paying company registration fees  
  - Appointing a CEO (who can be a local individual)  

3. **Opening a Bank Account:** After registering the company, open a bank account for it. Required documents usually include:  
  - Company registration documents  
  - Passports of directors  
  - Proof of address  
  - Business plan (in some cases)  

4. **Setting Up the Financial Cycle:**  
  - Foreign customers pay into your intermediary account in the third country  
  - You use the same account to pay foreign suppliers
