If someone from India wants to come to Norway because he wants to work here, and he likes the culture..then welcome.

How do you imagine it? The population of Norway is 4 million people, India - 1.5 billion. Find Norway and India in GDP/person table https://en.wikipedia.org/wiki/List_of_countries_by_GDP_(PPP)_per_capita . This is a tenfold difference in the level of living. If you open the borders, then 1% of migrants from India is enough for Norwegians to be in the minority in their own country. We must model the consequences, no more " welcomes" please. I suggest you read the book "The Mosque of Notre Dame". This is the forecast of what Europe will become soon, if nothing changes. A very exciting book, which describes in great detail the essence of Islam.
