Check the photo carefully. Inexpensive fakes sometimes bear a photo of someone who is not the person carrying the card. More sophisticated forgeries could feature authentic cardholder photos. In such cases, run your finger over the photo to confirm that it hasn't been adhered on top of another picture. Check the placement of the photo. On authentic green cards, the photo is located on the left side of the front. In the 2010 redesign, there is a holographic photo in the upper left quadrant on the reverse side of the card.
Examine the condition of the card by handling. Older cards and poor-quality fakes often have raised edges or have been double-laminated. Though better-quality forgeries do not have frayed edges, you can feel a slightly uneven surface, or even a line, where the card has been glued.
Look at the green card background. The newly designed green cards now feature a background on which the variable ink shifts from shades of gold to green. In addition, the U.S. government has added security features on authentic green cards using Radio Frequency Identification Technology. There also is a laser fingerprint on the card, which could be difficult for amateurs to reproduce.
Ask questions. A permanent resident card lists a person's U.S. Citizenship and Immigration Service identification number, the card's expiration date, and the cardholder's country of origin and date of birth. Often, if you ask a person to verify the information on a forged card, he or she hesitates slightly before answering or could give the wrong answer.
Ask to see another form of identification. If the person is carrying an authentic green card, all the personal information on both cards, such as the middle initial and date of birth, must match.
