The United States has several visa restrictions that affect whether a potential visitor is granted a tourist visa. Visa applications may be denied on the grounds of health, a criminal record or other security reasons. For example, anyone with a significant communicable disease or a physical or mental health disorder that poses a safety threat will not be allowed entry into the US.
The unofficial posture is that few people can afford to live without working for more than six months. Because people coming to the U.S. on B2 visas are not allowed to work, they will in all likelihood be issued a maximum six-month I-94. If the entrant is seeking medical treatment that may quite reasonably be expected to take more than six months, the determining officer can issue a one-year I-94 without consulting a supervisor. A traveler with a B1 professional visa, meaning they have work the State Department has already determined is acceptable under all its conditions, can stay up to three years on a single I-94. In an extreme circumstance, then, a person with a one-month B1 visa could legally stay in the USA for three years, not one month.

To circumvent this Arab League boycott of Israel, the Israeli immigration services have now mostly ceased to stamp foreign nationals' passports on either entry to or exit from Israel. Since 15 January 2013, Israel no longer stamps foreign passports at Ben Gurion Airport, giving passengers a card instead that reads: "Since January 2013 a pilot scheme has been introduced whereby visitors are given an entry card instead of an entry stamp on arrival. You should keep this card with your passport until you leave. This is evidence of your legal entry into Israel and may be required, particularly at any crossing points into the Occupied Palestinian Territories."  Passports are still (as of 22 June 2017) stamped at Erez when travelling into and out of Gaza. Also, passports are still stamped (as of 22 June 2017) at the Jordan Valley/Sheikh Hussein and Yitzhak Rabin/Arava land borders with Jordan.
Citizens of member states of the Association of Southeast Asian Nations do not require tourist visas to visit another member state, with the exception of Myanmar. Until 2009, Burmese citizens were required to have visas to enter all other ASEAN countries. Following the implementation of visa exemption agreements with the other ASEAN countries, in 2016 Burmese citizens are only required to have visas to enter Malaysia and Singapore. Myanmar and Singapore had agreed on a visa exemption scheme set to be implemented on 1 December 2016. ASEAN citizens are entitled to use the Burmese visa on arrival facility.
