Washington (CNN) The United States is on track to not admit any refugees in October, after already canceling around 500 flights this month, CNN has learned.

A pause on admissions that was expected to lift on Tuesday will now extend into November, leaving those who expected to resettle in the US in limbo. It also means additional travel will need to be canceled and re-booked at the expense of federal taxpayers.

The moratorium will run through November 5, according to a State Department spokesperson. "We will work with our implementing partners to plan for a resumption of refugee arrivals, including rescheduling travel for those affected by the extension," the spokesperson said in a statement.

It's the third time this month that the State Department has delayed refugee admissions. Travel for refugees who were told they could come to the US was postponed through October 21 , and then later to October 28 . There's usually a pause in arrivals the first week of October.

The Trump administration has proposed capping the number of refugees allowed into the US at 18,000, a historic low. But in order for refugees to be admitted in the new fiscal year, President Donald Trump has to sign off on the refugee ceiling. The consistent delays in travel suggests Trump has not signed it yet.
