Visa Renewal Recommendations

Anyone have a recommendation for a good place to get a B1 renewal near Dist 2? Is it better toy renew at the immigrations office or via an agent?

bta87, I just sent you a PM with a recommendation.

Sent you a pm with the agency which I usually do my visa with.
Located near the Pham Ngu Lao area so might be pretty convenient for you.

Thanks! Goy the PM's. Really appreciate it.
