I am entering my current mailing address, but US Virgin Islands isn't an option in the drop down menu. Where can I find it?

US Virgin Islands is an option in the "US possession" address category in the "My Info" section.  

1. In the "My Info" section 
2. "Edit" your mailing address 
3. In the box "Type of address" 
4. Select "US Possession" from the dropdown list 
5. The "State" box will then change to "US Possession" 
6. There you should find the "US Virgin Islands" option
