This is a list of all of the visitors to the International Space Station (ISS), including long-term crew, short-term visitors, and space tourists, in alphabetical order. ISS crew names are in bold. The suffix (twice, thrice, ...) refers to the individual's number of spaceflights to the ISS, not his or her total number of spaceflights. Entries without a flag symbol indicate that the individual was an American citizen at launch. Entries without a female symbol (
As of July 28,2017 [update] , 227 individuals have made 393 spaceflights to the ISS, including the six people currently at the ISS (Expedition 56). Two men made five spaceflights to the ISS, while five people made four, 29 people made three and 85 people made two. Note that this list assigns individuals with dual citizenship to their country of primary residence at time of launch (for example, the Iranian-American space tourist Anousheh Ansari is only listed under the United States).
All private space travel is aboard the Russian Soyuz spacecraft. When only two crew members are required in the three seat Soyuz, and additional cargo is not sent, the additional seat is sold to the general public through Space Adventures. Private travelers remain on the ISS during handover from one expedition crew to the next, generally a week or two. The NASA Space Shuttle carried seven crew members, and the longest docking with the ISS was 11 days. Many visitors to the ISS were accommodated for short periods during NASA shuttle dockings. NASA stated it was "not interested" in private spaceflight from the beginning of the ISS and has not changed its position. [1]

As of June 2016, Malenchenko ranks second for career time in space due to his time on both Mir and the International Space Station (ISS). He is a former Commander of the International Space Station.
Yury Valentinovich Lonchakov is a Russian former cosmonaut and a veteran of three space missions. He has spent 200 days in space and has conducted two career spacewalks.

Expedition 2 was the second long-duration spaceflight aboard the International Space Station, immediately following Expedition 1. Its three-person crew stayed aboard the station from March to August 2001. In addition to station maintenance, the crew assisted in several station assembly missions, welcomed the first space tourist Dennis Tito, and conducted some scientific experiments.
Soyuz TMA-7 was a transport mission for portions of the International Space Station (ISS) Expedition 12 crew launched October 1, 2005. The flight delivered ISS Commander William McArthur and ISS Flight Engineer Valery Tokarev to the station to replace Expedition 11 crew members. Spaceflight Participant Gregory Olsen joined the TMA-7 crew for the ascent and docking with the ISS, spent approximately eight days aboard conducting experiments, then returned to Earth with the outgoing members of Expedition 11 aboard Soyuz TMA-6. McArthur and Tokarev were joined on their return trip to Earth by Flight Engineer Marcos Pontes who launched aboard Soyuz TMA-8 and spent approximately seven days aboard the ISS conducting experiments for the Brazilian Space Agency.
Expedition 14 was the 14th expedition to the International Space Station (ISS). Commander Michael López-Alegría, and flight engineer Mikhail Tyurin launched from Baikonur Cosmodrome on 18 September 2006, 04:09 UTC, aboard Soyuz TMA-9. They joined Thomas Reiter, who had arrived at the ISS on 6 July 2006 aboard Space Shuttle Discovery during mission STS-121. In December 2006, Discovery mission STS-116 brought Sunita Williams to replace Reiter as the third member of Expedition 14. On 21 April 2007, López-Alegría and Tyurin returned to Earth aboard TMA-9. Landing occurred at 12:31:30 UTC.

TMA-15 was the 102nd crewed flight of a Soyuz spacecraft, since Soyuz 1 in 1967. The Soyuz spacecraft remain docked to the space station during Expedition 20 and Expedition 21 as an emergency escape vehicle. The mission marked the start of six-person crew operations on the ISS.
Soyuz TMA-17 was a human spaceflight mission to the International Space Station (ISS). TMA-17 crew members participated in ISS Expedition 22 and Expedition 23. The mission ended when the Soyuz TMA-17 capsule landed on June 2, 2010.
Expedition 22 was the 22nd long duration crew flight to the International Space Station (ISS). This expedition began in November 2009 when the Expedition 21 crew departed. For a period of 3 weeks, there were only 2 crew members; it was the first time that had happened since STS-114. Commander Jeff Williams and flight engineer Maksim Surayev were joined by the rest of their crew on 22 December 2009, making the Expedition 22 a crew of five.
Expedition 27 was the 27th long-duration expedition to the International Space Station (ISS), starting on 16 March 2011.
