Hello guys,
Just want to ask if it is really necessary to file for I-131, Application for Travel Document when applying for AOS - we're gonna mail our AOS package this week.
We're not yet sure on when to travel... and I saw that on the form we need to supply answers to date of intended departure & length of trip..
Thanks in advance
It's your option if your want to file for I-131
Eventhough the cost is included within the current fee schedule. However, you will have to decide whether applying form I-131 is worth applying for based upon your own situations and needs. Once the AOS is approved, the beneficiary ("Permanant Resident") may work and travel outside of the US. However, if you do not file the I-131 and your case is delayed due to an RFE or other reasons, you will have to wait for the AOS to be approved before the beneficiary can LEGALLY work in the US or travel outside the US without being denied re-entry.
About the 'date of intended departure and length of trip' you can assume both. We did, coz we're sure will be traveling sometime, although it may not be the exact date as listed on the AP.
For sure, anytime you want to travel you've an AP approval.
Good luck!
