Center near San Isidro, Costa Rica, and Santa Chiara Study Abroad Center in Castiglion Fiorentino, Italy. During the 2018 academic year, over 5,600 Texas A&M students—primarily undergraduates—studied in 110 countries. Marine research occurs on the university's branch campus, Texas A&M University at Galveston. It also has collaborations with international facilities such as Hacienda Santa Clara in San Miguel de Allende, Guanajuato, Mexico. The university is one of two American universities in partnership with CONACyT, Mexico's equivalent of the National Science Foundation, to support research in areas including biotechnology, telecommunications, energy, and urban development. The university also hosts Las Americas Digital Research Network, an online architecture network for 26 universities in 12 nations, primarily in Central and South America. Texas A&M has a campus in Education City, Doha, Qatar, which is part of Qatar's efforts to expand higher education with the assistance of elite institutions from the United States. Texas A&M University at Qatar (TAMUQ) was set up through an agreement between Texas A&M and the Qatar Foundation for Education, Science, and Community Development, which was founded in 1995 by then-emir Sheikh Hamad bin Khalifa Al Thani and his wife, who is the mother of the current emir Sheikha Moza bint Nasser. All degrees at the Qatar campus are granted by the university's TAMU College of Engineering. TAMUQ was opened in 2003, and the current contract extends through 2023. The campus offers undergraduate degrees in chemical, electrical, mechanical and petroleum engineering, and a graduate degree in chemical engineering. TAMUQ has received awards for its research. Texas A&M receives $76.2 million per year from the Qatar Foundation for the campus. In the agreement with the Qatar Foundation, TAMU agreed 70% of its undergraduates at its Qatar campus would be Qatari citizens. The curriculum is designed to emulate the academic rigors of the facility at College Station but critics question whether this is possible due to Qatar's strict stance on some of the freedoms granted to U.S. students. TAMU has also been criticized over its Qatari campus due to Qatar's alleged ties to Islamic terrorism and the country's human rights record. In 2016, Texas A&M Aggie Conservatives, a campus activism group, criticized the campus and called for its immediate closure on the grounds it violated a commitment to educating Texans and diminished the credibility of engineering degrees of students at College Station. In 2013, Texas A&M signed an agreement to open a $200
