So long as you have a valid ID then you are good to go. I heard that they are trying/have been trying to extend the date/deadline to Sept. 30. When you return you can apply for it here.. You only need a birth certificate to apply for a passport or its renewal. You can still travel with any form of valid ID. Good luck!
To apply: Puerto Rico-born Americans can apply online at http://www.pr.gov or pick up applications at Casa Guadalupe, 143 Linden St., Allentown, or the Hispanic American Organization, 462 Walnut St., Allentown. Completed applications can be mailed to: 171 Quisqueya St., Hato Rey, PR 00917
What to bring: A valid ID photo, such as a passport or driver's license
Cost: $5. Veterans and those over 60 do not need to pay a processing fee.
No you don't have to get the new birth certificate to travel
