After Valeria Do Vale arrived in the United States from Brazil as a 7-year-old girl, her mother sat her down. They were undocumented immigrants, her mother told her, and no one could know, but if Do Vale excelled in school and attended college, their family would prosper.

“We like to think it will be that easy,’’ Do Vale, 19, said Saturday in an interview. “It definitely wasn’t.

Do Vale, a scholarship student at Northeastern University, shared her story Saturday afternoon at a gathering in Jamaica Plain organized by a diverse group of teenagers who oppose President Trump’s policies targeting immigrant and Muslims.

The teens are part of collaboration between the Center to Support Immigrant Organizing, African Community and Economic Development of New England, and Margarita Muñiz Academy, a bilingual public school in Jamaica Plain, according to organizers.

The gathering at First Baptist Church included musical performances, skits about the immigrant experience, anti-Trump chants, and stories from youth who are immigrants themselves or the children of immigrants.

Do Vale, a member of the Student Immigrant Movement, told the crowd they must not let offensive rhetoric and policies divide them.

“We recognize the importance of being in solidarity with each other. Every step of the way, we are fighting for our Muslim sisters and brothers, for queer sisters and brothers, and for all underserved communities out there,’’ she said. “We’re also here to say Trump isn’t going to get his way.’’

Do Vale and Eriberto Mora, 22, who also performed at the event, have been granted some protections from the Deferred Action for Childhood Arrivals policy or DACA, which was established under President Barack Obama. Some illegal immigrants who entered the country as minors are eligible for the program.

Mora, a senior at Clark University in Worcester, said he worries Trump will rescind the policy. He came to the United States from Mexico at age 5 and serves as a youth coordinator for the Center to Support Immigrant Organizing.

“If President Trump takes away DACA, that means I’ll be back to being undocumented, which means I can no longer continue my studies, I can no longer work, and I’m at the risk of deportation,’’ Mora said.

Vidaly Cabral, 15, who was born in the Dominican Republic, said she has a green card, but still feels vulnerable and objects to Trump’s comments about Latinos.

“I still think I have to worry,’’ said Cabral, who lives in Dorchester. “We’re not trying to do anything wrong. We’re here to work and progress for our families.’’

She led the gathering in a chant in Spanish: “Me gusta la lima. Me gusta el limón. Pero ne me gusta la discriminación.’’ The translation is “I like lime. I like lemon. But I don’t like discrimination.’’

Ayisha Mahamane, 15, recited a poem called “Peekaboo,’’ which told the story of a Muslim woman being discriminating against for wearing the hijab.

Mahamane, a student at Boston Collegiate Charter School, said she has been wearing a hijab since she was 12 years old.

“Instead of covering my eyes, here’s what I did: I put a scarf on my head to see if you could see past it. And I wish that I could say you did well or that you lasted. But you called me a terrorist and a towel head,’’ said Mahamane as she recited the poem from memory.

She said she has been called a terrorist or taunted about wearing rags or towels on her head.

“I’m just like you,’’ she said. “I’m another person just trying to get through life, go to college, become a teacher, a doctor, any common career.’’

Alysha Vick, 16, of Dorchester, said her mother is from the Dominican Republic, while her father is Hispanic and Japanese.

“When I tell people that I’m part Japanese, they think I’m not actually Hispanic,’’ said Vick, a sophomore at Margarita Muñiz Academy. “They say I’m weird because I’m mixed.’’

She said she was heartened by the size of the crowd.

“Money cannot buy all the love that’s here and support,’’ Vick said. “Right now we’re making a change and fighting for what’s right. Remember we have the power to change everything.’’
