Hi Juanita,
I didn't agree with what you said about closing the doors to immigrants. If you think about it, you are an immigrant as well, unless you are Native American. As we all know that the White settlers came here long ago from Europe. So in this case, you too are an immigrant, and then is it fair to close all doors to the White people as well? Afterall this country first belonged to the Native peoples.
