I frequently travel to Guaymas, Mexico as a volunteer. I have often seen migrants, making their way north, at stoplights. Many have signs asking for assistance, or they offer to wash windshields for a small amount in order to purchase food. Help primarily comes from individuals, who may pass food or drinks out of car windows. There are no organized shelters in Guaymas even though it is along the busy Pacific route. I am aware of the disappearances of family members, drug related murders, and ineffectiveness of the government in Mexico keeping people safe. I understand the reasons for wanting to seek asylum I have noticed changes at the border crossing. The wall is now covered with barbed wire as is the "Welcome to the United States" sign. It seems like agents are intentionally slowing crossing.
Prior to moving to the southwest, I taught in a Title I school in the midwest with a high number of children from Mexico and Central America. Many had just recently arrived in the United States and had family support in the area. I didn't receive any specific training regarding the special needs immigrant children might have. i remember the principal grumbling about test scores and teachers bemoaning the lack of English spoken in the homes.
I also have a friend who spent last summer in Deming, New Mexico helping migrants from Cuba, Mexico, Central and South America. They had been released from a detention center near the city. The community stepped up and provided shelter, meals, clothing, and activities for the children. The shelter helped locate family members in the States and arrange travel. I wasn't close enough to help in person, just through donations. The stories my friend shared were heartbreaking.
