Costa Rica officials probably wish the country had a wall at the border.
Most Latin Americans were offended when Donald Trump suggested such a construction at the U.S.-Mexican border, but now Costa Rica is being invaded by migrants.
Hundreds of Haitians a day are managing to find their way across the southern border of the country, most likely with the help of human traffickers.
The Ministerio de Seguridad Pública said that its Fuerza Pública and the Policía de Fronteras are working to prevent migrants from entering Costa Rica.
Meanwhile at Casa Presidencial, officials there finally admitted that the bulk of the migrants are not really Africans as they claim but actually from Haiti.
In any case, their goal is to enter the United States as illegal aliens. Costa Rican officials seem to be prepared to help them do this on the grounds of humane treatment.
About 100 migrants a day are applying for and getting 25-day transit visas in the southern part of the country. Many more are evading police and immigration controls.
A.M. Costa Rica reported as long ago as May 25 that groups of migrants were making their way to Nicaragua by foot along the Caribbean coast. The newspaper also reported on the
complicity of local Costa Ricans in moving the group by boat from further south in Limón province.
The newspaper also reported that police in two nearby stations declined to respond to the matter.
There was an additional report Monday that Nicaragua has agreed to allow migrants to pass through that country. Lake Nicaragua was the scene of eight drowning deaths of migrants a week ago.
Unlike the 8,000 or so Cubans who headed to the United States from Costa Rica earlier this year, residents of Haiti have no legal right to cross the U.S. border.
That country has been suffering since the 2010 earthquake, mainly through mismanagement and corruption.
Another troubling aspect is that Casa Presidential officials speculated that the latest wave of migrants began their trip north in Brazil where they most certainly were exposed to the zika virus.
Under rules set forth Thursday, Costa Rican police officers are supposed to detain any migrants who do not have a temporary visa. So far there have been no reports of such detentions. But it is obvious that some migrants have official help. There also have been reports that some migrants have been able to obtain documents saying falsely that they are Costa Rican.
There are large numbers of Cubans and other migrants stalled in Colombia and also in Panamá.
