For two years and 27 days, Valeria Do Vale was just like everyone else in her college dorm: She had a driver’s license, a Social Security number, and, most importantly, a promise from the US government that nobody would deport her to Brazil.

That sense of security imploded on Election Day, when Donald J. Trump won the presidency after vowing to end the federal program that shielded her and thousands of other young immigrants from deportation.

So this week, she will board a bus of mostly women of color who are heading to the nation’s capital to ensure their issues are not overlooked at Saturday’s Women’s March on Washington. They are among those with the most at stake under a Trump presidency: immigrants at risk of deportation, people who fear racial profiling, and women battling both racism and sexism.

“The day I found out Trump got elected, it took me back to when I was 7. I had just come to the United States. I learned I was undocumented,’’ Do Vale, a 19-year-old college student, said in a Boston office building where demonstrators gathered Monday to paint signs for the march. “When I relived all the horrible things we had lived through in this country, I thought, I’m going to go through all of that again.’’

On Friday, she will be one of 55 passengers on a bus heading to the National Mall. In addition to the massive march on Washington, more than 300 sister demonstrations are planned in Boston and other cities in all 50 states, and some overseas.

Talia Barrales, a Boston immigration lawyer who was once undocumented herself, said she hopes the march on Washington will inspire immigrant families to keep fighting for legal residency. She recalled similar protests in California against Proposition 187, a state ballot initiative that sought to block families like hers from schools, health care, and other services.

Now, California has a slate of progressive laws protecting undocumented immigrants, and Barrales is a US citizen who helped pay for the bus to D.C.

“I hope that we are giving some kind of hope to my community,’’ she said.

Others called on state and federal lawmakers to better defend immigrants in Massachusetts, one of only six states where the unauthorized population has risen in recent years. The state is home to 210,000 undocumented immigrants, among 11 million nationwide, according to the Pew Research Center.

Although Massachusetts is a blue state, they say, it has not passed measures such as in-state tuition and driver’s licenses for immigrants here illegally.

And only one member of the congressional delegation, Representative Katherine Clark, has decided to skip Trump’s inauguration.

“Shame on them,’’ said Gloribell Mota, a former candidate for state representative who now runs Neighbors United for a Better East Boston.

She said other cities and states are defending immigrants, from creating legal-aid funds for immigrants facing deportation in Los Angeles and Chicago to allowing unauthorized immigrants to obtain driver’s licenses or pay in-state tuition.

“Let’s stop with the talking and show our actions,’’ she said.

Douglas Chavez, a political consultant who once worked in former governor Deval Patrick’s administration, said he believes that the women’s march will bother Trump, and show him that immigrants and others are willing to fight his policies.

“I think that it’s going to get to him,’’ he said. “I really do.’’

Others said they are hoping the march will unite people from a wide array of groups, from Muslims fearing a national registry to families worried about losing health care.

On Monday, the federal holiday honoring Martin Luther King Jr., volunteers gathered at the Student Immigrant Movement’s headquarters near Boston Common, turned up the music, and painted signs with slogans like “Without Women there is no Revolution’’ in Spanish.

Do Vale, the immigrant from Brazil who crossed the border when she was 7 years old, said she will not stop fighting until her mother and younger sister are safe from deportation. She said her mother brought them to America to flee an abusive husband.

In Boston, Do Vale was a straight-A student who got into one of the city’s elite exam schools and then won a full scholarship to Northeastern University. She received a work permit in 2014 under President Obama’s program to protect immigrants here illegally since they were children, called Deferred Action for Childhood Arrivals, or DACA — the executive order Trump has pledged to revoke.

Tears welled in Do Vale’s eyes. She said her younger sister is an even stronger student, and had hoped to apply for DACA this year.
