There have been restrictions on immigration from the time that the U.S. was formed.  There are several reasons for this.  I will give you three:\n\nStrict control of immigration protects our national security\nby keeping out spys and terrorists.  We relaxed our immigration laws incrementally from the 1930's and continuing to today and we have seen multiple terrorist attacks in that time.\n\nControlling immigration controls allow us to screen out the criminals and deadbeats.\n\nToo large an influx of immigrants at any given time could potentially cause our economy to collapse.

No need to conquer them.  Just ask them if they'd like us to annex them.  Put it up for vote in a Mexican election (We should allow Mexicans here to vote in it too).  America is great.  They know it, we know it, why not expand?

I feel that it is to get them started. It encourages competitiveness and the desire to improve on your product. It helped us get our industrial revolution going. However I feel that once a country becomes stagnant and lazy, resting on the accomplishments and inventiveness of the past...then it's outgrown Capitalism and should transcend it to another level of government. If you look at all the great civilizations of the past, Greece, Rome, Egypt and now America, they all reach a point when they lose that drive, desire and hunger to stick together and make things better. They sit back and let their empire crumble around them. Too self-involved with their own successes and monetary gains. If I had to put my finger on the next "America" it'd be a toss up between India and China. Watch the winds shift....you'll see it.

What would be a reason to colonize any land?  Why did the Indians come over here way back when the land was connected to Europe?   Hunger for food, wealth, saftey and life.   It is rather silly to equate our feelings and our present laws with the actions and rules that were prevalent in those days.   It was nothing at all to kill for survival and greed in those days.    The Native American also killed, pillaged and raped his neighbor for numerous reasons and it was an accepted fact.   I don't think you can find any other nation in the world that has coddled and repaid their indigenous people as well as has the USA.  Check it out!  Go to an old plantation in the south and look at the slaves quarters, then look at what they came from. Early death in the disease ridden jungles, right? They had it better here as slaves, except with bad slave owners, of course.  Think about it!

Only reason is cause, this is a "internal" problem. But that's how it is with dividing cities. Poors (in this case: illegal aliens), move to cities, than the middle to upper class move to the suburbs.\n\nIn conclusion, I don't think this will really stir much division of the U.S., because it's not like the Civil War. The illegal immigrationists aren't being used by the people who support them.\n\nAmericans will come to their senses, and support NO ILLEGAL IMMIGRATION!

Well, if the U.S. were to take it over we would double our landmass.  That's unique.  Plus it's the largest unguarded border in the world.

We were kind of trying to ensure the possibility for expansion.  The Europeans were no longer allowed to colonize, it would be considered unfriendly action if they tried.  And the U.S. stated again it's desire for independence to strive as a nation by telling the Europeans and Britain that they didn't want them interfering in American affairs.  They wanted to remain neutral in Europes war and feared Britain's ulterior motive of thwarting U.S. expansion.

You mean States?\n\nSimple. The railroads allowed for traveling farther faster and delivering needed goods as well.\n\nPeople could live further away but have supplies brought by train.

The only way that America is growing is through immigration. If it weren't for immigration, we'd have a zero or negative population growth.  Our country is graying rapidly--many older people and fewer young.  Without more younger workers, this country will not be in good shape in a few years.  I believe that immigration is good, necessary and as a country we should be thankful that people choose to come here.  People bring labor, brains and so much more.  As far as "legal" goes, it is always preferred that people do things legally, however, rules & laws change according to society's needs.  Perhaps the best answer here is to welcome the immigrant and change the rules as to what is legal/illegal.

It doesnt really matter if you are for or against it. It is only going to happen at an increasing rate as countries like China and India continue to expand their economies. For those that just take the attitude that think it is a bad thing, you are going to be left behind. You would be much better off to understand it and become part of it.

let's see, every time a new frontier of land was disovered, some poor race of people faced near extinction. \nThe Europeans have already slaughtered the Native Americans, enslaved the Africans, and oppressed the East Indians, and that was only for land. God forbid we find someplace with lots of oil because that'd be WWIII right there.

In a sense it never went away, it only expanded to a global level.  The goal of most (if not all) nations is to increase their own relative power and influence on the international scale, if possible to the exclusion of others.  The Monroe doctrine just codified this  by saying that America is "the boss" of the western hemisphere, however since WW2 our government has maintained a global military presence and become "the boss" of most of western civilization.

Because this is the US and we are expected to furnish the rest of the world with what ever they need. I am an immigrant who came here legally. And that's the way it should be.  I have seen what's happened England with open borders. The country is now a financial mess.
