Protesters outside of Portland's U.S. Immigration and Customs Enforcement headquarters are increasing efforts to help immigrants who miss appointments because the federal office is closed.

"We're the ones who shut the building down," said Jacob Bureros, an organizer with Direct Action Alliance, which helped plan the protest against President Donald Trump's immigration policies. "It's not their fault they can't get to their appointment."

ICE officials temporarily closed the downtown office Wednesday because of "security concerns" after dozens of protesters blocked the facility's entrances.

Translators and lawyers volunteered to assist anyone who showed up seeking ICE assistance, Bureros said.

Mary Ann Warner, of Portland, is helping coordinate translators and transportation out at the encampment.

She said four people came to the facility Friday, and about 10 came Thursday. Most were there to check in with the agency or update their addresses.

"My parents are immigrants, and the last thing I'd want them to experience would be missing check in," Warner said. "That's a terrifying place to be in."

Other volunteers will drive families to desired destinations, whether it be home or the ICE facility in Tacoma, he said.

Bureros said the camp continues to receive loads of donations, including money. Donations are being given to immigrants showing up for appointments as compensation for the costs involved in getting to the downtown facility.

He said some of these efforts started Wednesday, but a more concrete assistance plan was put in place Thursday night.

Tents now line the length of the ICE building at 4310 SW Macadam Ave.

"It's exploded; it's just massive," said Bureros, who estimated about 100 people stayed the night Thursday compared to about 50 Wednesday. He anticipates even more will join as the weekend arrives.

Friday's encampment plans include the invoking of Shabbat at 5:30 p.m. by members of the local Jewish community and the daily 8:30 p.m. candlelight vigil.

A "Not in Portland" protest is planned from 1 to 3 p.m. Sunday at the encampment. The agenda includes speeches by Reps. Diego Hernandez, D-Portland, Sheri Malstrom, D-Beaverton, and Rob Nosse, D-Portland, as well as a march and bike swarm.

Members of Occupy ICE PDX said Wednesday that they plan to keep the building surrounded until the Portland ICE office is permanently closed. Bureros said that plan hasn't changed.
