We should be having an open discussion about immigration and try to understand why so many people are fleeing from Latin America up to the US.
Every country needs to safeguard its frontiers in the best feasible way, for its citizen, immigrants, and neighbors' countries.
There is no easy answer to the question: What is the best policy?
Population displacement occurred because the risk of staying in a country is more than the risk of travelling in harsh conditions, mostly inhumane, plus adding the legal procedure at the destination.
The responsibilities for this are share between the governments from whose countries the immigrants left, second, those countries where they transit up to the destination and finally, the immigrants themselves. That is why there is no easy answer and, it will never be.
People fight for their rights up to an extent, pass certain point, citizen start to think in evacuate, because a person have a finite time (age) to build for his future, so it is reasonable that after a while, individuals feel that it is time to flee. Note that in this circumstance groups take advantage of doing illegal activities in both countries, add those who want to get into the country for that same reason.
Displacement is not new, historian and archeologist account for this phenomenon, one striking recent example is the Second War World, but wars are not the only reason for this. Other factors impulse movement of people in mass, for example: decrease on fresh water and food, extreme weather events, flooding, habitat loss, earthquakes, fires, volcanic eruptions.
A country needs to protect its citizen and culture, but by no means immigrants will endanger it if they are willing to accept and integrate with their new “home,” more over it will enrich the culture, for example with culinary art, music, and literature. But for this to happen, the immigration process shall have planification and resources.
Now a days with globalization, this problem (human displacement) is for all. The key is to help poor countries to develop themselves, but the foremost tricky part is corruption which is exceedingly difficult to account for in poor countries. The only way for them is to have strong and independent institutions, separation of power and a judicial system.
At the end, the key word in all of this is Corruption.
