Present-day Western people didn't colonize the Muslim countries, and they are not responsible for what their ancestors did. Otherwise, the ancestors of Muslims did much worse to non-Muslims as compared to what the Western colonial powers did.
The crimes of the ancestors of Muslims include:
- They made non-Muslims their slaves.
- They took their women and raped them.
- They didn't even spare their small children and made all of them slaves for their entire lives.
- They also took all of their wealth and properties (and didn't leave even a single penny for their opponents) and brought 100% destruction upon non-Muslims.
Ibn 'Aun reported: I wrote to Nafi' inquiring from him whether it was necessary to extend (to the disbelievers) an invitation to accept (Islam) before meeting them in fight. He wrote (in reply) to me that it was necessary (only) in the early days of Islam. The Messenger of Allah (ﷺ) made a raid upon Banu Mustaliq while they were unaware and their cattle were having a drink at the water. He killed those who fought and imprisoned others (and turned all of them into slaves).
As compared to the 100% destruction of ancestors of Muslims, the crimes of the Western Colonial powers were milder. They didn't take Muslim women and children as slaves and didn't rape Muslim women and girls. They didn't plunder their wealth and properties completely.
So, if the present-day Muslims are not responsible for the crimes of their ancestors (right from the era of Muhammad), then the present-day Western people are also not responsible for the crimes of their colonist ancestors.
And there is absolutely no law which demands that present-day Western People allow Muslims to immigrate to their countries. It is only due to the HUMANITY and Secular Values of the present Western People (to be concise, the secular left-wing parties) that they welcome Muslims to their countries, allow them to marry their women, and have equal human rights.
If the right-wing parties come to power in the Western countries, then they will immediately stop any immigration from Muslim countries, as the Muslim excuse of "colonialism" is not going to work anymore.
If you are still unable to see the humanity of the majority of Western People, then just look at what the rich Arab countries do to their fellow Muslims.
But many religious Muslims are, unfortunately, ungrateful.

The fact that we did it because of HUMANITY and for the sake of every human deserve human right say something. The west open their border just because they are human. WE ALL ARE HUMAN. They didn't do it because they will get something in afterlife. They didn't do it because they are afraid of god. And then all the muslim said the atheist doesn't have morale. Like hell nah bruh, we do good thing because you are human, I'm human and we are all human. That's it. Not because I will get 72 virgin in heaven or something.
