Information concerning reciprocity agreements between the U.S. and other countries can be accessed via the State Department’s website at http://travel.state.gov/content/visas/english/fees/reciprocity-by-country.html.  For each nation, the table shows applicable nonimmigrant visa category, visa issuance fee, the maximum period of visa validity and number of entries that may be authorized.

It has been a subject of debate as to whether maintaining these reciprocity limitations further United States diplomatic interest worldwide, and serve to the benefit of American travelers overseas.  The debate will certainly continue long after President Obama’s visit to China, but in this instance, it was a valuable diplomatic tool.
