To point out the importance of S. 610. let me cite several crucial facts which were brought out in the hearings: First. in 1958. earnings from foreign residents visiting the United States ranked fourth among U.S. commodity exports. second. expenditures by U.S. residents for foreign travel in 1958 exceeded those for any other U.S. commodity import. third. in 1958. as measured by comparative government budgets. the United States ranked above Cyprus. but below Singapore. the Philippines. the Belgian Congo. and Czechoslovakia. in government spending for official travel offices. It seems to me that whatever actions we take to reduce the travel gap. each action is based. either implicitly or explicitly. on a theory concerning such questions as why there is a travel gap. what are the barriers to foreign travel. and what are the best means for reducing the gap and removing the barriers. As I see it. the barriers to foreign tourism in the United States include lack of information. visa and currency restrictions. and the cost differential. The enactment of S. 610 should help to reduce each type of barrier. For example. the publicity program which S. 610 proposes can help to remove the information barrier. it can remove some of the mistaken ideas of how expensive it is to travel in the United States. and it can inflame the foreign tourists already existing desire to visit the United States. The Office of International Travel can. in conjunction with other Government agencies. work to make what visa and currency barriers exist more favorable for foreign travel in the United States. Of the various causes for the lack of foreign travel in the United States. I feel that the costdifferential factor is probably the most important and perhaps the most difficult barrier to remove or to lower.
