Pros
I am with Numbers Only Inc for 8 plus years.
They paid me on time, despite the vendor payments. I like the Online Website that shows Employees Account Balances.
CEO of the company (Hari) is very friendly, and extends strong Immigration support to any one in the company that I know.
Administrative Staff Provided me the documents promptly. Without their help ontime, I would not have got my GC. Helped with RFEs, which is the major support one needs.
I referred few of my friends/colleagues, when they had tough time in 2009 (they got Laid Off from their Full times at client place). Now they are feeling lucky and very happy because of Green Cards process and got EAD's, and their families working :)
I believe in "PATIENCE PAYS". In October 2013, my Green Card is approved.
Cons
Very Minor and they can be ignored
