Klaus' statement about him not being able to buy guns because he isn't a US citizen, "I can't buy guns at a gun store, but I can buy them online and at gun shows", is likely poking fun at one of President Joe Biden's many incorrect statements made during speeches. In one interview Biden stated that online gun retailers and gun shows are a danger to the nation because people can buy guns from them without going through a background check, he said "you can buy a gun online, and it's mailed to you with no background check or you can walk into a gun show and buy a gun and no background check". Both statements are absolutely false and incorrect, they are misinformation and scare tactics spread by anti-gun groups. At one point in the past there was a loophole in the law that allowed guns to be sold at shows without background checks, but that has not been the case for many years, the Brady Handgun Violence Act of 1993 closed this loophole, all guns shows are now required to do background checks before selling a gun. Same goes for online gun retailers, you cannot buy a gun online and have it shipped to you, instead the gun is shipped to a gun dealer that has a valid Federal Firearms License (FFL). After payment is processed the website then ships the gun to a FFL dealer of your choice, once the gun arrives at said dealer they notify the buyer, who then comes to the store and undergoes a federal background check prior to the gun being turned over to them, if the person fails the background check the dealer sends the gun back to the online retailer. The only kind of guns that can be bought, either online or at a gun show, without requiring a background check are antique style guns like black powder muzzleloaders.
For an alien non-resident to become a United States citizen they must first spend at least five years as a lawful resident of the U.S., or three years if they are married to a U.S. citizen; being a lawful resident means being granted a Permanent Resident (Green) Card. Other requirements are being at least age 18, being able to read, write and speak English and being of good moral character (not having any outstanding warrants or serious criminal record). Following this if a person meets all the requirements they then take the Naturalization Test, which consists of two parts: a civics test that covers basic U.S. history and basic knowledge of the Constitution and a basic English comprehension test. Following successful completion and passing of the test the individual is then interviewed by a Immigration caseworker about why they want to become a U.S. citizen and what they plan on doing. Once all this is complete the individual then takes the Oath of Allegiance to formally become a citizen.
