A new feature added to the I-94 website (How Much Longer May I Remain in the U.S.?) allows VWP travelers to check their admission date, and informs them how many days they have remaining in the U.S., or how many days they have remained beyond their expiration date.
In addition, to prevent an overstay, the CBP now sends an email reminder 10 days prior to the expiration alerting the VWP traveler who remains in the U.S. that his I-94 will expire.
These new features are available under the “View Compliance” tab on the I-94 website. Travelers should expect to receive email notifications from Staycomplianceemail@example.com, and CBP warns that any email not originating from this address may be fraudulent or a phishing scam. CBP is going to email from @CBP.DHS.gov email address.
