how old are you ? ... most countries will have a 'travellers' type visa upto a certain age .. i dont think your supposed to 'work' on them but starbucks will take anyone ..
other than that most places operate a points system. eg
age = # points, the older the less you get
money = #, they dont want spongers
skills = #, fire eating, being able to make a cappacino which is all froth, nurse, plumber, 6th sense for finding womd etc. a skill they need at that time will score high, like nurses, but not IT people
etc .. you need to have x amount of points and then you can start the application process.
if you can get a job offer then your normally sorted. another way which is good for oz and nz is a franchise visa, where you agree to buy a franchise in something .. back to starbucks again !!
good luck its not quite as easy as it seems ..
