Yes, yes. The USA was built on the foundation of immigrants. That core value of what makes America America must never be forgotten.
There's a security risk, yes, but closing borders is not the solution. The terrorists will find there way in, no matter what, and instead you are denying millions of potentially good citizens an opportunity. Isn't that what the USA is - the land of opportunity?
Not to mention, gun violence from American citizens leads to thousands of times greater deaths than any terrorist attack.
So, it's up to the security agencies in USA to step up, screen the immigrants thoroughly. Make sure terrorists are neutralised.
But millions of good, hardworking people must not be denied.
