I have a Work Authorization and state id that states temp resident not allowed for re-entry and I traveled to Puerto Rico! It's U.S territory!! You must book one way flights. I suggest waiting until the official documents are out for travel before thinking about it. Advanced Parol is not a good option for anyone that was here unlawfully! It triggers a 3-10yrs bar if you leave. Although, they will let you in the U.S with it...when the time comes for you to adjust status to permenabt residence you maybe denied. I say wait fit the new forms to come out in 2 months before you think you have a chance to travel. It's not worth it unless the fine print days it won't be held against you in the future. Going to Puerto Rico is ok on flights that don't connect to other countries. If your plane lands in another country on route to the US...you're ficked!!!
