There is plenty of interest in the area you want to probe. My own sense is that your intention for the "supporting questions" backfired. I look at this and think: "This Q is basically = Everything I Ever Wanted to Know About Immigration in Ancient Israel -- And I'm Not Afraid to Ask!!"
Either blow away your "supporting Qs", or rewrite them as background information to show "research effort". (I recommend the former, FWIW.) It ought to be clear to potential answerers that they do NOT need to deal with these aspects, and the way it's currently framed looks rather like an invitation to treat them. Fergedaboudit.
Or ... do some further research first, then "zoom in" on particular passages to fill out your understanding of this area. There are several related areas intertwined in your question, at least these, possibly more:
- the status of the "stranger/foreigner" in "biblical Israel". The most important Hebrew terms here are ger ("sojourner") and nokri ("foreign[er]"), and you could explore passages where these terms occur.
- the nature of amalgamation of non-Israelites into Israel -- the best narrative examples here are Rahab (Joshua 2, 6) and Ruth (contrast Joseph in Gen 37-50, who turns up in Egypt [as it were], speaks Egyptian, and [eventually] is regarded as an "Eypgtian").
- the status of "borders" in antiquity, especially the ancient Near East (obviously), rather than "classical" antiquity, although one might expect some continuity here.
- the nature of "national identity" in antiquity, although this is a contested concept according to some who see (erroneously, IMHO) the rise of the "nation state" only with modern Europe.
- the attitude displayed to foreign nations throughout the Hebrew Bible (one famous example: contrast, e.g., Deut 23:1-8 with Isa 56:3-8 -- but there are plenty of other passages to consider).
There is a substantial scholarly bibliography on each of these areas. Perhaps this begins to suggest why the way you've formulated the question using Deut 19:33-34 as a starting point, with its attendant sub-questions, begins to look a poor fit for the StackExchange Q&A model, which necessitates well-focused questions ("be specific"!) in order to work.
