Have you considered the UAE? I worked there for a while, and it really is a great place to continue a career internationally, especially with being from the UK. It’s safe, the money’s good, the weather is great, and you make a lot of international contacts that can only help further your career. Also, a company will (in general) have all your visa sponsorship stuff, and in some cases accommodation, done before you land, so the transition is quite smooth. The caveat is that you are (for the most part) stuck with the company you work for. Some companies have 6-month to a year of a non-compete clause built into the contract. You can move to a different position at a different firm, but the process is usually long and can be costly. I know a few firms that ask you to leave the country “for some time” while everything gets settled. Check out Naukri for a whole bunch of positions. As I’m sure you can appreciate, the events industry in Dubai, Abu Dhabi, Muscat, and Doha is quite large. You might be spoiled for choice
Canada is a good option, too (but I might be biased because I’m Canadian). Only issue is that the beginning is quite a struggle, especially in a place like Toronto. Companies here work you pretty hard, and rents are pretty high. Also, you’re usually on the hook for any expenses related to a work visa, residency, etc. That being said, once all that red tape stuff is done, you are completely mobile throughout the country. If you’re in event planning, however, I’d recommend sticking to one of the bigger cities. Montreal, for one, is great…and contrary to popular belief you don’t really need to speak French to live there. As far as online resources for work in Canada, I’ve found indeed.ca, monster.ca, and glassdoor.ca to be the best. I think they all exist in the UK as well. Recruitment companies that hire international people do exist here, but their focus is on cheap labour (and I wouldn’t recommend going through them at all as they’ve been getting scammy recently).
I’m rambling because I’ve spent 98% of my professional career working abroad (Japan, India, Poland, Oman, the UAE, the UK…).
Hope all goes well for you. I can try to help you with any other questions you might have, so feel free to write back!
