Apologies for the belated response to this: I'd missed the alerts that someone had responded to this thread.
@Jared: Given the presence of Turks in the *USA, I would like to know how the *USA views Middle Eastern peoples in general.
Short answer is "better than non-White Hispanics, but not well." The USA has a racial hierarchy which implicitly has American whites at the top, other whites second, East Asians off to one side, Indians a special case, other "brown" peoples as they see them further down and best kept out if in any numbers, and "blacks" at the bottom.
To put it in more detail, it is quite true that *Americans focus on keeping African and Latin Americans "in their place" means that they are less worried about other peoples. However, this is largely a function of the fact that they don't perceive any threat by these peoples. If there was particularly large-scale immigration, then this would be more of a concern.
In other words, the *Americans are not overly concerned over a few Turks or other Middle Eastern peoples coming to *America, because they don't need to be. There aren't many, and the general *American attitude means that not many more want to come.
For those who do want to come, Middle Eastern people who look vaguely "white" by *American standards will do better, as will those who are Christian. So OTL Lebanese Maronites will do reasonably well if they can pass for the (more relaxed ITTL) *American standard for white. Jews are also more acceptable due to familiarity by now, though this means
less prejudice rather than none. Muslims who face the double barrier of being non-Christian and non-"white" will fare the worst.
America and Non-White Immigration
As Jared has noted throughout DoD, East Asians and Indians are not the subject of *American hatred because of their focus on Africans and Latin Americans. Also, there has been a small amount of migration from Asia after the Great War, mostly from former German Formosa as seen in #114d. With the gradual acceptance of Asians as honorary whites, might the *Americans consider opening the door to large-scale immigration from Asia, especially from regions occupied by the Restored Empire & allies, the foes that *Americans dislike the most due to the Great War and ideological rivalries? Or will the potential influx of not-white immigrants who are outside the hierarchy of anglo-ladino-negro trigger a reaction?
This is similar to above, with the caveat that most East Asian and Indian migrants end up congregated within key locations within a few key cities. They are not viewed as much of a concern because the *Americans who live near those locations (the "Chinatowns" and equivalents) are more familiar with them, and there aren't generally that many. Step into rural *America and there would be less familiarity and potentially more hostility, particularly for those Indians who would be considered darker-skinned by *American standards. Not "throw them into peonage" level of hostility, but definitely less welcome.
