>How expensive/difficult/limiting is it if you need a visa for a lot of locations? That depends. If you go somewhere like Thailand, you fill one-page form, glue your photo and send passport, said form and 40 dollars in envelope to consulate, then pick it up on your way to airport. If you go somewhere like US or EU - that's kind of humiliating. You pay ridiculous fee, fill long form on terribly designed website, travel to another city for interview and have 33% chance to not get it without any explanation. For EU you also get to gather ton of bullshit papers from bank, insurance company, hotel, airline and your local employer for single trip.
