@Anduy F can you travel out of the country with no problem coming back to the US with the combo card?

@Jorge Alberto Yes. the 1-512 that is located at the bottom of the card is exactly the travel document. below is a copy passed I did from the approval notice I received from uscis. It will give you more details. We have approved your application for employment authorization and advance parole based on your pending Form 1-485, Application to Register Permanent Residence or Adjust Status. We will send your Employment Authorization Document (also known as an EAD card or Form 1-766) to you separately. The EAD card will have an 1-512 endorsement on it, which indicates that you have been approved for advance parole. Your EAD card should be produced within one to two weeks. Your EAD card will be mailed via U.S. Postal Service (USPS) Priority Mail with Delivery Confirmation to the address you designated. The time frame in which you will receive your EAD card may vary, depending on USPS delivery times. Please allow a total of 30 days from approval before inquiring with USCIS. We encourage you to use Case Status Online https://egov.uscis.gov/ to find your USPS tracking number for EAD card delivery. If you have not received your EAD card within this time frame, please visit https://egov.uscis.gov/e-request/intro.do for instructions on how to submit an inquiry. Advanced Parole The 1-512 endorsement on your EAD card is proof that, while your Form 1-485 is pending, you may travel abroad without abandoning your Form 1-485. Show your unexpired EAD card with the 1-512 endorsement to the ship or airline, and it can let you on board to travel to the United States. As long as your EAD card has not expired, you may use it multiple times to request parole into the United States. U.S. Customs and Border Protection (CBP) can parole you into the U.S. for up to one (1) year.
