It's funny how you guys pick and choose when to use "undocumented" vs. "illegal". That being said, she had a visa. Nobody disputes this. Some people are saying she had a visitors visa vs. a work visa. The fact is, she had a visa and was here legally. The question is if she was paid to be a model, should she be here on a visitors Visa. She could sell her labor legally, even if she didn't have a work visa.
A B-1 Visa is primarily for business purposes, a B-2 Visa is primarily for pleasure or medical treatment, a B-1/B-2 Visa is for both.
There is absolutely nothing that suggests she was here illegally. Nothing.
If you don't have a permanent employer that is specifically sending you to the US solely for the purpose of business, you should be here on a B-2 Visa. Models are not typically hired for permanent employment (more than one year). So she likely wasn't really permanently employed by the photographer or magazine, and was likely a freelance model who worked with several agencies. So it wouldn't be appropriate for her to apply for a B-1 Visa.
This story is really all just a bunch of nonsense fabricated by leaving out necessary facts hiding behind "it appears" or "was she" or that kind of blatant obscurity. Those who write their blogs know the facts, but ignore them to put the story out.
...and Libraryanna isn't a retired lawyer, she's only ever claimed to be a retired legal assistant until you asked this question.
