if you already hand over your resume and you hear nothing from them, it would not harm you to call them instead for follow up :).. i agree with ingeniero, give an ad to a local newspaper,or post you CV online, let your friends here knows that you are looking for a job, so they can tell it to their friends' friends and friends.. lol, be patient, if still nothing happens, i guess you have your luck somewhere else :) But then again, i hope you find a job soon.. Goodluck!
