I think you are ignoring the time to PR part.
EB1 current processing time is 8 month (and you have to have 1 mil) the requirements are very strict
You can buy a 500K property in Cyprus/Portugal etc and become resident (latvia 250K)without any requirement to run a business or hire people etc.
Cmon H1B is done once a year and there is lottery with 50% chance of wining (spouse can not work)
E visa are business visas and only for people from treaty trader countries plus they do not convert to PR
L visas you have to work for the subsidiary for 1 year there is a limit on L visa length
In Czcech Republic, Estonia etc. you need 10K to get residency through business and there are no requirements to hire people etc.
I am not ignoring anything. I have tried both hiring into the EU and from EU to the US.
Also you need to make the proper comparison with EU not just cherry pick a few countries. I can cherry pick countries to where it's very hard (try Denmark for instance).
My claim was EU vs US again 11 million illegal immigrants living here and for a large part contributing to the economy that alone would never happen in the EU.
And you don't need 1Million for a EB1. It's a merrit based greencard (just like O1 visa is)
Exactly coming from outside of EU you can become a resident of EU state that has simplest procedure and yet after that you are able to work and live in any EU state which makes immigration to EU trivial compared to US.
