When he was with IRS' Office of International Operations, he worked out of US Embassies and Consulates all over the world, including France, Switzerland, Mexico, Venezuela, Brazil, Argentina, Guam, etc. He lived in and worked for the IRS in Puerto Rico for close to three years. He speaks fluent Spanish. His wife and law partner is from Puerto Rico. He is also fluent in Lithuanian, his native tongue, and belongs to several Lithuanian or Baltic associations, including Chambers of Commerce and Bar Associations.
