And your second citation says nothing of the sort with regards to immigration, it is solely examining the affects of geography within a country as it affects conflict both religious and ethnic.

The second citation doesn't examine the effects of 'geography', but the effects of borders and boundaries between ethnic groups, finding increased conflict where those boundaries are missing.
Furthermore, this discussion is about the overall cost/benefit calculation, so your point about the paper saying there are benefits does not preclude what the above comment stated.
Like it or not, in the USA cash is king. It is what people optimize for.
If you FIX a highly-rewarded measure for a nontrivial time period, the "take best comers" approach kicks ass. As long as your fix apriori and them measure. That's what we see here. GDP was defined before current immigration policy was set, after all.
If we have faults, they are in our system for doling out rewards. Not in the color/creed/religion of the people we let compete for those rewards.
If you want better social cohesion, design social systems to REWARD that cohesion. Then, communities will offer what you seek. To your great surprise, I suspect, those communities will be highly diverse.
Otherwise, you end up with sub-populations that severely under-perform on actually measured metrics and go out to search for bullshit alternative (under/arbitrarily)measured metrics by which they win. Again, that's what we see in your comment.
It seems crazy to me that this fact isn't part of the table stakes for any debate about US immigration. This isn't a liberal or conservative argument, it's just an acknowledgement of the fact that there's no precedent in living memory for the current number of foreign born, non-citizens living in America.
It's possible to stake out many positions based on these facts. Depending on your persuasion you could argue that the road to citizenship needs to be easier because we're creating a disenfranchised underclass; or you could argue that America is under assault from foreign influences; or you could argue something else. But it seems like this hugely relevant fact doesn't even get discussed in most public or policymaking discourse.
I think this is happening in a lot of countries, the capital cities in particular attract a large diversity of population. I was curious so spent a few minutes exploring figures.
In London 36.7% are Foreign-Born, rising to 42.2% for Inner London. [0]
Paris is about 21% [1]
Berlin is 18.4% [2]
New York city is 36%, Los Angeles is 41% [3]
In 1976, less than one in four Sydneysiders was foreign born. Forty years later the figure is nearly 40 per cent. [4]

My opinion: I am a believer that immigrants are the lifeblood of America and are the secret sauce that make it great. It's a nation for immigrants, by immigrants. I think we should encourage immigration on the basis that brain power is the resource that US needs and one that will be driving the growth of the next century.
That's a good argument for legal merit based immigration but not for illegal immigration or the majority of legal immigration that is family based.
What the MSM buries, immigration is a mixed bag, immigrants are not a magical people that always benefit citizens in the US. Of course on the negative side, Americans in the most vulnerable position take the hit.
One can be pro immigration but acknowledge this, and advocate for policies that encourage high skilled immigration.
I know older people who made $30/hr out of high school at local factories with full benefits thanks to unions in the 70s and 80s. Illegal immigration was used to break those unions and today those jobs pay $10-15/hr with no benefits
The biggest reason why wages have gone down has been the decline in union membership since it is only through collective bargaining that you can force wage rises.
Or when demand for labor outstrips supply, as in tech (for the moment).
because illegal immigration destroys any negotiating power of unions. You can't go on strike when there are millions of illegals that will take that job
On a less theoretical point the US and Switzerland both have much lower unionisation than comparable countries and are much richer. Canada, France, Germany, Italy, none look good compared to their richer, more unionised neighbour.
I believe a different question needs to be asked which is. What conditions need to be in place before immigration becomes a net positive or a net negative.
It's always struck me as an important difference that the US is so attractive to people even though they don't get anything compared to Europe.
I remember when I grew up in Denmark and we had discussions about why immigrant/refugees got free bikes and free metrocards to take public transportation.
This turned into a kind of resentment where every time you saw an immigrant doing well you would often hear "well of course since they get everything from the government" The sentiment is that it's less deserved.
There is something about access to better opportunity which transcends the actual state of that opportunity as long as it feels deserved which I believe is what actually helps a country get more out of its immigration even though if it's system isn't as generous as ex. the Scandinavian or German immigration systems.
The US system could be much better but the opportunities here are still second to none IMO (I moved from Denmark because of better opportunity for what I want to do with my life)
Immigration is at times great for a country at other times can be a problem depending on the state of the situation the country finds itself in.
Looking at it statistically just isn't the right way to do things. It will always be a mix and doesn't really make sense to talk about net benefits in any truly meaningful way IMO. Only context matters.
