Marilyne Tatang, 23, crossed nine borders in two months to reach Mexico from the West African nation of Cameroon, fleeing political violence after police torched her house, she said.
She plans to soon take a bus north for four days and then cross the tenth border, into the United States. She is not alone - a record number of fellow Africans are flying to South America and then traversing thousands of miles of highway and a treacherous tropical rainforest to reach the United States.
Tatang, who is eight months pregnant, took a raft across a river into Mexico on June 8, a day after Mexico struck a deal with US President Donald Trump to do more to control the biggest flows of migrants heading north to the US border in more than a decade.
The migrants vying for entry at the US southern border are mainly Central Americans. But growing numbers from a handful of African countries are joining them, prompting calls from Trump and Mexico for other countries in Latin America to do their part to slow the overall flood of migrants.
As more Africans learn from relatives and friends who have made the trip that crossing Latin America to the United States is tough but not impossible, more are making the journey, and in turn are helping others follow in their footsteps, migration experts say.
Trump's threats to clamp down on migrants have ricocheted around the globe, paradoxically spurring some to exploit what they see as a narrowing window of opportunity, said Michelle Mittelstadt, communications director for the Migration Policy Institute, a Washington-based think tank.
"This message is being heard not just in Central America, but in other parts of the world," she said.
Data from Mexico's interior ministry suggests that migration from Africa this year will break records.
The number of Africans registered by Mexican authorities tripled in the first four months of 2019 compared with the same period a year ago, reaching about 1,900 people, mostly from Cameroon and the Democratic Republic of the Congo (DRC), which remains deeply unstable years after the end of a bloody regional conflict with its neighbors that led to the deaths of millions of people.
'THEY WOULD HAVE KILLED ME'
Tatang, a grade school teacher, said she left northwest Cameroon due to worsening violence in the English-speaking region, where separatists are battling the mostly French-speaking government for autonomy.
"It was so bad that they burned the house where I was living ... they would have killed me," she said, referring to government forces who tried to capture her,'' she said.
At first, Tatang planned only to cross the border into Nigeria. Then she heard that some people had made it to the United States.
"Someone would say, 'You can do this,'" she said. 'So I asked if it was possible for someone like me too because I'm pregnant. They said, 'Do this, do that.'"
Tatang begged her family for money for the journey, which she said so far has cost $5,000.
She said her route began with a flight to Ecuador, where Cameroonians don't need visas. Tatang went by bus and on foot through Colombia, Panama, Costa Rica, Nicaragua, Honduras and Guatemala until reaching Mexico.
She was still deciding what to do once she got to Mexico's northern border city of Tijuana, she said, cradling her belly while seated on a concrete bench outside migration offices in the southern Mexican city of Tapachula.
"I will just ask," she said. "I can't say, 'When I get there, I will do this.' I don't know. I've never been there."
Reuters spoke recently with five migrants in Tapachula who were from Cameroon, DRC and Angola. Several said they travelled to Brazil as a jumping-off point.
They were a small sampling of the hundreds of people - including Haitians, Cubans, Indians and Bangladeshis - clustered outside migration offices.
Political volatility in Cameroon and the DRC in recent years has displaced hundreds of thousands of people.
People from the DRC made up the third-largest group of new refugees globally last year with about 123,000 people, according to the UN Refugee Agency, while Cameroon's internally displaced population grew by 447,000 people.
The number of undocumented African migrants found by authorities in Mexico quadrupled compared to five years ago, reaching nearly 3,000 people in 2018.
Most obtain a visa that allows them free passage through Mexico for 20 days, after which they cross into the United States and ask for asylum.
Few choose to seek asylum in Mexico, in part because they don't speak Spanish.
Tatang said the language barrier was especially frustrating because she speaks only English, making communication difficult both with Mexican migration officials and even other Africans, such as migrants from DRC who speak primarily French.
Those who reach the United States often send advice back home, helping make the journey easier for others, said Florence Kim, spokeswoman for the International Organisation for Migration in West and Central Africa.
Like their Central American migrant counterparts, some Africans are also showing up with families hoping for easier entries than as individuals, said Mittelstadt of the Migration Policy Institute.
US data shows a huge spike in the number of families from countries other than Mexico, El Salvador, Guatemala and Honduras at the US southern border.
Between last October and May 16,000 members of families were registered, up from 1,000 for the whole of 2018, according to an analysis by the MPI.
The gruelling Latin America trek forces migrants to spend at least a week trudging across swampland and hiking through mountainous rainforests in the lawless Darien Gap that is the only link between Panama and Colombia.
Still, the route has a key advantage Countries in the region typically do not deport migrants from other continents due in part to the steep costs and lack of repatriation agreements with their home countries.
That relaxed attitude could change, however.
Under a deal struck with the United States last month, Mexico may start a process later this month to become a safe third country, making asylum seekers apply for refuge in Mexico and not the United States.
To lessen the load on Mexico, Mexico and the United States plan to put pressure on Central American nations to do more to prevent asylum seekers, including African migrants, from moving north.
For the moment, however, more Africans can be expected to attempt the journey, said IOM's Kim.
"They want to do something with their life. They feel they lack a future in their country," she said.
