Go to the US Department of State Website (travel.state.gov) to get all kinds of travel information, including: Passport and International Travel Information

Do I need a visa?
By looking at the International Travel Information and clicking on the Country Specific Information , you can locate the information for specific countries. Usually it will list entry requirements and contact information for their embassy in the USA. Embassy.org is another resource for locating Washington DC embassies. The best time to call an embassy is in the morning because they are usually closed in the afternoons. You may be redirected to contact a Consulate office which serves the Iowa region.

Passports
If you need to apply for a passport you may do so at the Decatur County Auditor's Office at the Court House in Leon. You may contact them directly for details at 641. 446.4323  

Passport photos may be taken at the Courthouse Auditor's Office for $10 or at the Creative Media Center (CMC) in the basement of Zimmerman Hall. Contact them at 5249 to make arrangements.
