Relocation, advices ?

Hello everybody, today i wanna talk about relocating for designers\artist

I’m a exhibition stands designer, currently living at Ukraine.

I really want to move, my preference USA\Canada\UK.
I currently playing USA Green Card, which is good opportunity to relocate without big amount of problem like if you want work visa.

My skills good enough for this field, but nobody want to help with visa sponsorship, i had conversations with designers from different places around the world, but everyone have same problems ( notwithstanding some of them are veryyy good at design field)

Did anyone had relocation experience and can give some advice ?
