Traveling abroad while I-129 is pending

[Bingo124]

I work from home. My home address has changed. My office address is the same as 

 

before. The company filed an LCA and an amendment to H1B. The petition is now pending 

 

since Sep 11th. I need to travel abroad on Nov 14th. Visa stamping date is Dec 3rd. I 

 

am flying back to the US on Dec 14th.

 

1) Can I travel on Pending I129? I am hoping that the petition would be approved by 

 

Dec 3rd as the current processing time is 2 months. After approval they can mail the 

 

I129 abroad and I cna attend the visa stamping interview.

 

2) Apply for premium processing. I might have to shell out money from my pocket. 

 

ALAS!!! what is the timeline of approval on premium processing?

 

3) Any other solution?
