Hi,
I studied in New Zealand (not in law). Dependent on what country you are from the process to gain entry to the country requires medical clearance(which can be a long and expensive process). As far as employment goes-once again there is a process to gain a work permit/pr. Cost of living is high and dependent on what area you end up with ie North Island (auckland) is more expensive than the South Island (Dunedin). Good luck.
