The employment situation in Miami is pretty diverse which means there is a bit of a safety net that is currently keeping the city afloat. There are cities across the country who are not nearly in the same great financial condition that Miami is and for that, anyone who is looking for work in the city, should be thankful for.
As there is this little buffer between Miami and most of the rest of the US, I think if you are looking for a job there you should put your best foot forward. Go into everything thinking positive thoughts and you will find the job you are looking for. It just takes a little time.
