I agree with Scorpion..why didn't your brother just provide you with a family visit visa or a hotel/tourist visa instead? It's easier to come here with those visas. Better yet, if you want to work here then apply legally through an agency to secure a working visa.

The Phil. immigration is quite strict nowadays with people holding business visit visas as they are aware of the MOs of some people with business visit visas who are coming here to work. If you don't have supporting documents to present or if you cannot confidently convince them that you are coming here for business purposes then you will certainly be offloaded.....but then again you know how it is back home...money talks:)
