First of all, if you move often and apply to jobs in various countries, some recruiters take note of that; they probably assign you a flag in their system that says that you're 'willing to relocate' so you often get offers for lucrative overseas contracts sometimes in low-tax (or no-tax) jurisdictions like Gibraltar, Dubai... Another benefit is that if you see a company you like, you know that you can just go work for them at their HQ wherever they might be. Really good companies are often the ones which attract talent from all over the world. If other talented people are prepared to fly half-way across the world and leave behind all their friends and families on a short notice to work for a company, then you know that this company is almost certainly doing something special.
