One of my colleagues is a British man who just gained his US citizenship in 2021. He's been here since 2007 on a marriage visa. And prior to that, he has described the immigration process as "arduous."
And getting married is apparently the easy way to get in.
When I fly, I fly from Oklahoma City. Getting through OKC is a dream. Hardly anyone flies out of here. Tix are usually cheaper flying from DFW. In my experience, you have to leave really early, maybe get a motel room, and it costs at least another $70 worth of gas to get there. It's so much extra cost and inconvenience. It's actually been cheaper overall for my wife and I to fly from OKC since we live here.
It's like 30-45 minutes getting from your car to your boarding area. Getting through TSA is always pretty quick and easy. I can't imagine the place is solvent.
Mint and Kubuntu are great for newbies. Ubuntu is also great, but the community hates Ubuntu these days so be ready to get replies criticizing Ubuntu or your choice to use it. It still makes a lot of shit really easy.
