This is the case with virtually every immigration system in a developed country. If you don't have the right or some sort of indefinite leave (e.g. PR, green card) to live and work in a place, then your visa affords you the right to stay temporarily for a specific purpose: working, studying, traveling, etc. The real problem with the H1B system IMO is the uncertainty and inconsistency of everything which leaves those affected in a constant state of concern.
