Our US Supreme Court needs to know their limits

Today I found on the internet that our US Supreme Court has decided that undocumented immigrants have the same right to keep and bear arms just like US Citizens do. This means that the millions of foreign citizens/documented immigrants/undocumented immigrants can legally own pistols and rifles in our country.

Just like Mexico, Canada, China, Ukraine, Russia, and all other countries, America is a sovereign nation. Our Constitution and Bill of Rights apply to American citizens only, not to citizens of other countries. I don't believe the designers of our Constitution and Bill of Rights wanted the US Supreme Court to have right, power, and authority to control citizens of other countries?

Foreign nationals are not American citizens. Our US Supreme Court does not have the authority to grant foreign nationals ANY of our rights.

Of the approximately 5 million new immigrants, how many of the immigrants had a thorough background check done on them? How many are violent gang members? How many are violent criminals? Even if 99.9% are decent law-abiding folks that just want a chance at a better life, that means that about 50,000 bad persons have entered our country since 2020. Do you want those 50,000 bad persons granted the right to own guns? I do not.

While I do not have any control over the US Supreme Court, I am running for president in 2024 and when elected I will close our borders to the extent that only the immigrants we want in our country will pass our border.
