Got approved in 4 business days in Hanoi (business owner). I provided an overabundance of supporting documents including six months of bank statements and documents from my state government showing how long the companies have been in existence. It was much faster than I was expecting.
I won't leave Hanoi for a couple of weeks so no report yet on how smoothly the transition through airport immigration went.
Overall I think it is a process that doesn't come close to requiring the use of an agent.
