My fiancée just called HCM consulate and met a nice Vietnamese lady who told her our interview date is 7/23/2008. We are so happy!
In the mean time, I want to share my experience in obtaining packet 3 at HCMC. I hope it will help people who do not want to wait long for Packet 3.
Notice in my time line that we have Package 3 sent even before we received it. This was possible because we obtained our Package 3 through an immigrant service in Ho Chi Minh City. These services possess all the forms contained in Packet 3 and they also help your fiancé(e) fill out the forms. They are not lawyers and we can selectively pick a specific service, so the cost is cheap (it costs my fiancée only 250,000 VND ~ $15). The guy who helped my fiancée told her that she could submit Package 3 as soon as she has HCM case number assigned.
Good luck to everyone on your visa journey.
