According to the latest plans, undocumented immigrants who will be approved for the so-called RPI immigration status visa as part of the Border Security, Economic Opportunity, and Immigration Modernization Act of 2013 (BSEOIM), will receive a tamper proof, secure smart card, similar to a green card (there is no plan to actually paste a document in your passport so when you check in at an airport outside the United States to travel to the US, you will present both your passport and the RPI card as proof that you are authorized to travel to the US) While it has been very easy to forge Social Security cards, this new card will have the latest technologies that will make in nearly impossible to forge it. All the data related to your identity and legal immigration status will be embedded in it and can be downloaded by a reader. So when you arrive at an airport or border check point, the CBP officer can see almost all your details with just a swipe or tap (while the officer may not put a stamp in your passport when you enter the United States, you will still be required to carry your passport with you). You will also use this card to show to an employer that you are authorized to work in the United States. The card will be used by you while applying for a driver's license. It can also be used as an ID to board a domestic flight or buy alcohol or enter a bar and wherever else you are required to show your identification in case you do not have a driver's license. If stopped by a police officer or at a checkpoint, this card can be used to prove that you are legally in the US.
