There are several options to get more information from the USCIS. There’s an online virtual assistant called Emma that answers questions based on the topic you enter. The information is available in English and Spanish.
There’s also a 24-hour automated phone system for general questions asked in English or Spanish. The number to dial for automated help is the same as the one for appointments.
If you’re looking for information, then it’s best to check the USCIS site first because it covers most topics. Besides English and Spanish, some information is available in other languages, including Arabic, Chinese, Braille, etc. Also, before applying, make sure you locate the field office serving your area.
