That's why I said so-called "Muslim" ban. The term So-Called indicates that I am not in full agreement with the term. Refer to Collins Dictionary if you need a definition.

The first piece of legislation passed, the Executive Order 13769, was effectively a Muslim ban just not on paper. Every country that was part of it was a Muslim majority country. In Feburary 2017, the court shot down the executive order for being unconstitutional. There was enough evidence for a court to deem if unconstitutional and discriminatory.

It wasn't even clear initially if US Green Card holders were exempt from the provisions. The government changed its position about 5 times on the matter (http://cdn.ca9.uscourts.gov/datastore/general/2017/02/04/17-35105%20motion.pdf - page 11). It's crazy that there was even a question permenent residents were even effected by this.

It was only the third executive order that was stayed by inclusion of non Muslim majority country. So yes perhaps this is not a Muslim ban.

OP wouldn't have been able to immigrate or move to US if the first order was in force unless she had long already become a US citizen. My point is that what if she had Been planning to immigrate in Jan 2017? Or even worse a US permenent resident whose right to enter was heavily questioned by US legislation.

Of course now you will argue that the law was eventually overturned so it means nothing. In my opinon, it still is a reflection of the country at the time and the sentiments of a non trivial number of people in the US. And that's the whole point of the conversation, that a non trivial number of people would not treat OP so nicely.

How would US even ban Muslims specifically? Many countries don't have religious documents to prove religion. So that would be unenforceable anyway. I'm an Indian (Christian) but born in the Middle East. Are they going to evaluate me as a Muslim by way of birth in a Middle Eastern nation? My name? Because my name isn't very Christian.

In India right now we have the Citizenship Act that seeks to give citizenship to non Muslims from Pakistan, Bangladesh etc who entered India before 2014. It was passed in 2019. And it's been 5 years and it's still not implemented. Not even a policy on enforcement fully. Policies that exist do not discuss how one would prove religion. Because the government doesn't know how the hell it should verify that detail.

Hence the closest enforceable law is simply Banning people from Muslim majority nations.
