Hi everybody I am atm technican and have diploma in information technology and 1 and half year certificate in electronics and other special certificates.so please help me to get the job.

What country are you from?

Most countries will have pretty strict requirements for hiring someone outside of the country and it can be difficult and costly for them to do so. You would likely have to apply to the specific company (check websites for various companies) and hope they will be able to get a work permit for you.
Another route might be to get hired by a company where you live that has international offices and perhaps at some point you might be able to obtain a transfer.
