The Communists are looking to create a single-party country forever, that's why they want these immigrants.
The US allows a million people a year to join our country as citizens. We give out that many work VISA's and green cards for outsiders to take advantage of everything we created. We have a limit on immigrants so they don't flood our country and change it to theirs. A million immigrants a year plus workers gives them time to assimilate so they change for us.
Thanks to Democrats and sell out Republicans, they are coming here by the multi-millions and are changing our country. Our signs are now bilingual, our voting ballots are now bilingual, and our government and even private institutions hire bilingual workers to cater to these invaders. Their children hold up our children in school. So this is why we had limits.
