I need to reschedule flight, waiting on Re-entry permit

[Summer1375 0]

Hi all, 

I've received the Notice of Action for my I-131 application for travel document process I started for my mother, just a couple of days ago. It says:

 

Next Steps:

 

USCIS will schedule a biometrics appointment for you to have your biometrics electronically captured at a USCIS application support center. You will be receiving a biometric appointment notice in the mail with the specific date,  time and place where you will be having your fingerprint and/ or photographs taken.

You must wait to receive your biometrics appointment notice before going to the ASC.

 

Her flight was this coming Sunday, I need to reschedule it but I want to know how long it takes to receive the appointment date/ time letter in the mail and estimate date of appointment. 

Please help!

You are typically scheduled for biometrics within a couple of weeks of submitting the application.

So I will be safe to delay her flight around 6 weeks? I know it's not guaranteed but I don't want to reschedule it again, it's too expensive!

That would probably work. 

 

Or you could just wait for the appointment so you don't have to guess.
