I-131 help

[mafia29 0]

I have been recently told that I'm not spending enough time in the US and must file for an I-131 travel document.

I come back every 4 months, for about 2 weeks. I'm away at school and will be back in the US for good by next august.

I have a few questions i'm hoping someone can answer!

- Is this travel document a one time thing or can i re-enter multiple times for the period of 2 years that it is valid?

- How long does it take to process the initial application once filed and to recieve a date for biometrics?

- Seeing as how i am currently out of the country and will be returning mid december, i'm hopeing to file now and recieve a letter to show up for biometrics around the time i will be in the US. If however i can not make the scheduled time, can i re-schedule? or can i just show up the office with my letter and hope that they take me? ( i did the later for my biometrics of my greencard, it was a slow day and i came at almost close, so maybe i can do the same for this)

- Once my biometrics is done, when and how will i be issued this I-131? Because I won't be in the country very long, will it show up when my passport is scanned, or must i carry an actual physical document with me?

That's pretty much it, if anyone has anymore insight into this, i would appreciate it very much.

Thanks,

M
