Hi traveler16, really appreciate your response.
I will take your advice and wait into the middle of next week. There is some urgency in my case, my beneficiary is literally stuck on a ship (as a crew member) and his contract is ending soon, so he has to be dropped off somewhere. They are willing to drop him off in the US, but if theres no travel authorization its going to complicate the process and he might have to be dropped off somewhere else.
So far I have been patient and not reaching out to them, even though initially i was confused when I didn't get an email within 24hrs (silly me), but eventually I am going to have to turn up the pressure. In your experience does communication with a Tier 2 office actually prove to be useful? Do they have the ability to push the case forward especially since it's stuck at some error on their part.
Also when you say "within their norms" what are their normal timelines for the 2nd email? Their website does not have any processing timelines for I-134 forms, so i'm in the dark in terms of what is within their permissible timelines.
thank you!
