i would ectually instruct in florida...get up to 1000 hours...and then ...direct to Tanzania....or west africa...
if you come to africa with 270 hours....i see it difficolt to get a job ..not to mention that sometime...bush flying can be quite difficolt...
on the other side....you can try your luck...you just need lots of patience and skill...which is something that you could build in florida...to me sound a bit better like this.
all the best
