United States: According to USCIS, this is the proper way to submit forms by mail

Using the United States mail to mail USCIS forms is currently an option. If you must go that route, you should know that if a form was submitted online, it should not be sent through the traditional messaging mechanism.

The USCIS provides citizens with an extensive list of recommendations to minimize errors and doubts that can arise when you need to send paperwork through the mail.

The entity indicates that the forms can be downloaded and printed free of charge from the web page containing all forms. Likewise, you can request forms that cannot be submitted online at the Forms by Mail site.

These tips will help you ensure that your application or petition package is accepted for further processing.
