Finding work abroad through an agent can be helpful, they will support you through your journey, sometimes the fee is paid for by the employer but even if you pay yourself, there are lots of benefits to using an agent. They can arrange your visa, health insurance and help to find somewhere to stay.
Some people prefer to go to their chosen place of work to explore what the opportunities are and connect with a recruiter before they leave. You may want to consider a working holiday visa, some travellers are eligible for this, please check as each country will have its own rules and regulations regarding working visa.
Voluntary work abroad is also an option, however, you will not be paid and sometimes you will be expected to cover your own expense like accommodation and flights. Since it is so much you can get out of this experience volunteering is definitely one of best ways to work abroad you get to do something useful, be part of a team and make a contribution to people’s lives, this would be great for developing your social and communication skills.
