If you are American, 19 is too young to have a degree, so you are out of luck
in getting a work visa.

If you are Canadan, Australian, New Zealander, or British, you don't need a
degree to get the working holiday visa, but you will still need to put up a
fair amount of money.  Check your embassy.

If you are trolling, congratulations on your catch.
