Compile an extensive list of questions about local culture, geography and history before hiring a translator. Note short-hand names for restaurants, mountain trails and local attractions during repeat trips. This initial test should help eliminate inexperienced translators and frauds who try to take advantage of foreign travelers.
Request information from the U.S. Embassy in a foreign country about trustworthy local translators. The State Department utilizes translators in hundreds of countries around the world to deal with local disputes and diplomatic crises. You can access a list of foreign embassies via the U.S. Department of State website (see Resources below).
Contact graduate school programs specializing in foreign language to hire a translator familiar with locales on your itinerary. International students who attend foreign language and culture programs at schools like Washington State University may be eager to earn money between semesters by serving as translators (see Resources below).
Acquire the services of a local translator who possesses connections to area businesses, tourist sites and community members. A translator who works in a local industry like farming, skiing or construction mobilizes connections to smooth your group's path.
Determine the literacy level of local translators before making a decision about whom to hire. A translator who can read, write and speak at a high level may cost twice as much as a villager, but she can help you avoid awkward situations with local officials.
Arrange for local translators in every region during your travels to address changes in dialect. Translators in Spain, Italy and other European countries with multiple dialects charge between 30 and 60 Euros per hour for extended translation services.
Approach translators offered through travel companies with caution before hitting the road. These translators may not be paid well for their work, which makes the level of quality variable. Request references for translators arranged through your travel company before accepting their services.
