Maria del Carmen Serdan High School, Puebla, Mexico
San Juan Tianguisminalco is a small town in Puebla, Mexico.
The school lies in the shadow of the volcano
The people survive mainly by cultivating flowers, but almost a third of them try to cross the border and stay as immigrants in the United States.
Most of them travel to New York, which is known informally as "Puebla York", and work as cleaners, gardeners, painters, builders and in the hospitality sector.
The María del Carmen Serdan High School was created in 1997 in a small building in the main square. It had 12 students.
The school has since moved to a new location near the Popocatepetl volcano, and it has 37 students.
Some of the pupils are eager to travel there to work as labourers to help their families in Mexico to get out of poverty, although the school director says that this is not common among the ones who actually finish their education.
Most of them know someone who has crossed the border ilegally.
Gage Park High School, Chicago, US
Chicago is home to the third largest Hispanic population in the US.
Gage Park has 1,700 students
In the past 35 years, the population has quadrupled, and more than 1.3 million Latinos have been born or have come to work there.
This growth is reflected in the 1,700 students of Gage Park, a public high school on the south-west side of Chicago.
The school has a large first, second and third generation Latino population. It also celebrates Mexican festivities and events such as 5 de mayo.
