All foreign nationals who are registered and are 18 years or older must carry proof of registration or face criminal penalties, including fines of up to $5000 or imprisonment for up to 30 days, or both. We recommend that all noncitizens carry with them one of the following, as applicable: I-94, I-485 receipt notice, or employment authorization (work permit). Green card holders are required to carry their actual green card with them at all times (this is not a new requirement). While A and G visa holders are exempt from this requirement, we recommend that they carry proof of their status as well. This is most easily done by I-94.
