Yes but does "race" not matter at all? I don't know how law abiding Indians are, but let's say they are exemplary, won't it change the character of the country if they are let in en masse regardless? Or say if they are African Catholics, with supposedly the same values. People will still naturally divide themselves based on color in many cases. An Indian boss will naturally be inclined to hire other Indians and so on. I think even the avowed color blind civic nationalists very well understand this but just can't bring themselves to say race matters.
Race is Real, not an artificial construct! 
Is this a good development?
"The U.S. population was around 90% White around 1940, it is not 40% White today. As of 2022, Non-Hispanic Whites make up about 58.4% of the population. The population is more racially and ethnically diverse due to shifts in immigration patterns since 1965, which opened up immigration from countries in Latin America and Asia."
No. Race is irrelevant. The problem with the African or S. American or Mexican immigrant to the US has a lot to do with the behaviors that are taught, encouraged, tolerated and indoctrinated AFTER they arrive in the US of A.
Even if they arrive as wholly immoral, filthy, violent, savages, if the conditions in the US were different, a return to values, return to common sense, reasoning, civic debate, education, those savages would assimilate to the expectations of society. Most of the bullshit that is spouted by the left and/or right is X "ism" whether its race, religion, ethnicity, gender, etc.(but to be 100% clear most of the bullshit comes from the left).. its taking the abhorrent behavior of some and attributing it to all. Or let's say taking the behavior of most and attributing it to all.
Unfortunately 'cultural Marxism' has destroyed the last 2 generations of white Americans, victim hood and lack of any accountability has destroyed the last 2 generations of black Americans. And its roots began even further back.
Immigration has always existed. There is nothing wrong with legal immigration. But if you begin your American journey by breaking the very first law you encounter , you will not respect the country, its laws, its people or its history. And if you don't respect those things specifically the law and its citizens, then you can't be tolerated. You must get the fuck out. I would even say if you have a shitty criminal record, you shouldn't be allowed entry in the first place.
But we live in. Backwards times. We have politicians, elected officials, who are behaving worse than most immigrants act. To quote a well known politician "we are a nation of immigrants but we are also a nation of laws." And we have mayor's and senators and governors and representatives who are openly encouraging violence toward law enforcement, advocating law breaking, threatening the president, or many are even openly racist. The problem isn't the country or color of the immigrant, the problem is left wing politics.
My beliefs would probably be different if I lived in France or Germany or many European countries that have gone to shit. Those countries should maintain their heritage, history, customs and above all protect themselves from the invasion. But The U.S. has to have some respect for our own history and recognize that a nation of immigrants can exist successfully, can assimilate, tolerate each other given how we all got here (native Indians notwithstanding.)
