I applied for US travel visa as a citizen of Poland in 2012 and was denied travel due to "wrong type of visa". I was planning to visit my employer and spend 1-2 weeks traveling across the country. Apparently both business and travel visas were inappropriate for these purposes. To add, I was questioned in a US consulate/embassy (can't remember) in Warsaw by a person who repeatedly refused to speak in English, insisted on Polish and I, as a native Polish speaker, had issues understanding them. Poor experience.
This was not a case for Swedish citizens, which is mentioned at the beginning of Daniel's linked post. Sweden is a member of ESTA[1] and Daniel traveled to the US multiple times before being denied travel (with still valid ESTA) and only then applied for a visa.
Yeah. I treat one-man small business serving mainly one big client to be comparable. On paper it's B2B, in reality it's working for the client and if the client is small business' main source of income, it's pretty much an employment.
Differences, in Poland at least, are that small business owner in this scenario is not protected by employment laws (3-months notice layoff, max 3 months salary-equal damages liability etc) and uses company's (EU)VAT registration number instead of personal social security number equivalent (PESEL number). It eases abroad contract agreements, invoicing and allows serving more clients easily. Company existence can also be validated on EU VIES[1] website quickly.
In the visa case, I have of course used the "paper" phrasing as in reality I was, and am, only employed by my own small business.
