Also, whilst by law persons enjoying the right of freedom of movement are not to receive a passport stamp, in practice, upon request, a stamp may be given – see the gallery below for an example of an entry stamp being issued upon request by an EU citizen. Similarly, although by law heads of state are not to receive a passport stamp, in practice, this is not always followed. For example, when arriving for the 37th G8 summit in Deauville, United States President Barack Obama had his passport stamped at Deauville – Saint-Gatien Airport. Similarly, when President Obama attended the 2009 Strasbourg–Kehl summit, his diplomatic passport was stamped on arrival at Strasbourg Airport on 3 April 2009, and after visiting Prague, Czech Republic, his diplomatic passport was stamped on departure from Prague Ruzyně Airport on 5 April 2009.
