sajha keto..just join the client without thinking. as you know how the dhoti vendors are..there is a chance to get the audit in perm if the company is not that good and also after you get the perm they will wait for 5 and half months to file the i-140 and that is also in the regular processing..no PP and that will take another 6 months and then wait for some more months to file i-485... so I would just join client if I were you.
