Do You Need I 94 if you have green card?
No
Does I-94 Automation Apply to All Entrants to the U.S.?
No. First, I-94 Automation applies only to nonimmigrants. U.S. permanent residents (green card holders) are not issued I-94s of any kind. Second, for now, the I-94 Automation program applies to entrants only at U.S. airports (including U.S. immigration preclearance facilities located outside the U.S.) and at U.S. seaports. I-94 Automation will not apply to nonimmigrants entering the U.S. at a land border port of entry. Third, certain classes of foreign nationals, such as refugees, asylum applicants, and parolees (persons “paroled” into the United States, including persons presenting Advance Parole travel authorization), will continue to receive a paper Form I-94.
