Shelters providing aid and refuge to migrants seeking asylum in the United States are running low on supplies as the holiday season approaches.

The volunteer-run facilities are said to be overrun by the sudden surge of migrants crossing the US-Mexico boarder who are in need of temporary housing.

Shelters say the US Immigration and Customs Enforcement (ICE) is no longer helping migrants with travel plans - releasing them from their custody whether they have places to stay or not.

Non-profit groups and churches are now scrambling for clothes, diapers, cots and meal donations for the stranded migrants as the holidays approach and resources begin to dwindle.

The Trump administration has been releasing detained immigrants at a faster rate than usual, according to the shelters. The President spoke to reporters ahead of the G-20 summit in Buenos Aires on November 29

The desperation for reserves has been linked to the Trump administration's decision to release detained immigrants from Central America at a quicker pace than usual in recent weeks, putting a strain on shelters from San Diego to South Texas.

In some cases, volunteers are picking up migrants from train and bus stations after getting dropped off by immigration officials.

On other occasions, shelters are being surprised by busloads of migrants arriving at their front doors.

One exhausted migrant, Alonzo Juan Jose, has spent six-days sleeping on the concrete floor of an ICE detention facility with his 5-month-old daughter, Allison, as they wait to be released.

'I just want her to sleep,' said the 24-year-old, who spent a month walking from Mexico to El Paso, Texas, carrying his daughter.

But now, heading to a migrant center in Les Cruces, New Mexico, for their first goodnight sleep in nearly a week, the duo are just one of hundreds of families in desperate need of aid.

A temporary shelter in San Diego has housed more than 1,500 asylum seekers awaiting the outcomes of their case, since opening in October.

Immigration and Customs Enforcement began releasing more people before they could arrange travel to family and friends in other parts of the country, said Kate Clark, an immigration attorney in San Diego.

One day last week, ICE released nearly 100 people, bringing the number of migrants staying at the shelter to 178.

Church leaders in the Phoenix say ICE has released about 5,000 migrants in the last two months to local churches.

Volunteer shelters along the U.S.-Mexico border have asked for food and clothing donations to help cater for the influx of imigrants. Guatemalan migrant Cirila Alejandra Calelpu and her family rest at Cathedral of the Immaculate Heart of Mary migrant shelter in Las Cruces, N.M, on November 29

They say they have had to scramble to find diapers, clothing and food at the last minute. Most of the migrants dropped off at churches or shelters leave within a day or two.

Previously, ICE officials have said the agency lacks the resources to house the growing number of migrant families crossing into ports of entries in California, Arizona and Texas, and they have begun releasing them to nonprofit shelters and churches in the area.

Shelters say they are preparing for a surge of new immigrants seeking asylum in the U.S. as the holiday period approaches. Young men climb over a fence in Tecun Uman, Guatemala, as thousands of Central American migrants rush across the border towards Mexico on Oct. 19, 2018.

Sylvia Corona, one of the volunteer coordinator at Immaculate Heart of Mary, said the network of shelters in southern New Mexico and West Texas believes the demand will continue to grow in the coming weeks.

'I think we're going to see hundreds of families needing places to stay,' Corona said. 'We're opening up two more shelters soon. We're letting them stay in our own homes if we have to, but we'll find something.'

In the meantime, Immaculate Heart of Mary and others have set up Amazon.com registries to facilitate donations like baby clothes, paper plates and coats.

Annunciation House, an immigrant shelter in El Paso, Texas, is asking for packets of underwear and socks.

The shelters house the migrants until they are able to make other travel arrangements.

The call for donations has hit communities far from the border and has used the migrant caravan to highlight the growing need, although not all migrants are connected to the caravan that has garnered international attention.
