A "consul" is a person within the government who is in charge of relaying information about and promoting his country within a foreign region, while the "consul general" is the government official in charge of supervising all of the lower level consuls within a certain area. If you would like to write a letter to a consul general, you should first understand exactly how to properly address her to ensure you are polite and respectful in the letter.
Start with the word "Dear." This is a universally accepted polite greeting for a letter.
Add the consul general's title, such as "Mr.," "Mrs.," "Ms." or "Miss." Note that if you're not sure if a female consul general is married, use "Ms." to address her.
Write in the surname, or last name, of the consul general. Then, add a colon to complete the greeting.
For the envelope, include the consul general's full name after his title and write "Consul General" underneath his name.
