It is true that if you work as a full time (Direct company) and you're in H1 and you get Layoff then you're DONE ! That's the risk being with direct company and H1. That' happens with most small companies. When they run out of business or their business slows down then they'll let you go and that's really scary.

The good thing about desi consultancy is that they'll hold your H1 even you're done with one project and looking for another and you've a gap in between.

They'll save you.

You decide now !

But as far as the benefits and everything else goes, i'd definitely consider Direct Full time Job.
