Good afternoon all. I am in the process of renewing my Non-immigrant OA visa for another year. I've recently talked to a few visa providers here who claim they can provide a one-year renewal in 3 days with no money transferred, at prices between B 20,000-30,000. My inclination is to do it myself at immigration (and I'm pretty clear what's required, thanks to this group), but wanted to ask if anyone has had any experiences with this type of service and can relate their experiences, and if so, can you recommend a provider who did a good job for you, in case I choose to go this route.

Many thanks!
