@rockhamster But it also implies and encourages a transition to green card and then citizenship - both of which free the employee. It can also be transferred to a new employer - though it's a hassle.
Whereas other types of working visas actively discourage transition to a green card, and very firmly tie the employee to that specific company.
@TomF yes that's true. There are some even more restrictive so yes it is better than them. I was thinking more compared to other countries.
@TomF @rockhamster What makes you think so?
Montenegrin employment visas are non-transferable and never lead to a "green card". Swiss ones require crazy stays to be able to switch to a "green card" equivalent.
