To fly a Complex A/C like an Arrow in the states requires a complex endorsement by an FAA instructor. most places won't let you take one away unless you have around 25hrs complex, or 5 hrs dual in their A/C [due to insurance requirements]. An FAA Complex is an instructor sign off and could possibly be done in an hour. If you have no previous complex then might as well use the full 5hrs for the endorsement....
