Brazil has delayed the start of visa requirements for visitors from Australia, Canada and the U.S. to April 10. The requirement was set to begin next week as a visa waiver for those three countries expires, but Brazil pushed it back while it works to complete implementation of an electronic visa platform and to avoid “interfering with the flow of tourists from these countries to Brazil during the high season,” according to Embratur, the Brazilian Tourist Board. The waiver is expiring as the three countries have not established a reciprocal visa waiver agreement for visitors from Brazil, a stipulation of the original waiver.
