Taylor and other officials on a conference call for reporters declined to say what countries would be affected or even whether it would be fewer or more than the six cited in the travel ban. The Department of Homeland Security employs nearly 2,000 people in about 80 countries around the world screening high-risk travelers seeking to visit the United States.
The Trump administration has reportedly been drafting a new order with travel restrictions tailored to roughly eight or nine countries that could replace the ban signed by the president in March that targeted six majority-Muslim nations.
This summer, the US notified all countries of certain baseline verification standards, that is, the individual identification information and information the country must provide related to public safety and national security, and gave countries 50 days to come into compliance.
"Quite frankly, the screening and vetting status quo for border and immigration security is not adequate", Taylor said.
Now, Trump must choose whether to adopt those recommendations or modify them.
The Justice Department, the State Department and DHS are all reviewing various options and planning on how to implement the next phase smoothly as Trump weighs his decision, a White House official said.
This second decree was halted by two district court judges, but in June the U.S. Supreme Court allowed it to come into effect for 90 days. Trump during his campaign called for a "total and complete shutdown of Muslims entering the United States".
The travel ban was first announced in January, days after Trump took office.
The original travel ban included restrictions on entry into the United States by refugees from around the world.
The officials declined to say which or how many countries would be targeted.
Justice Department spokeswoman Sarah Isgur Flores said the department was continuing to defend the executive order but could not comment on the ongoing litigation.
"The goal is to protect Americans until foreign governments do comply with our standards and no longer pose a risk to the welfare and the security of the United States".
They said he could decide to add more countries to a list that aims to keep terrorists out of America but has been criticized as overly broad and unnecessarily punitive.
Others however "were wilfully non-compliant and unwilling to engage with the United States".
What do you think of the travel restrictions?
Under the recommendations Trump is weighing, new restrictions on US entry would differ by nation, based on whether they are willing to adopt new USA security mandates, Taylor said.
The officials also declared victory from the original travel ban, saying that the process has pushed a number of other countries to begin sharing more information about their citizens who are seeking visas to enter the U.S.
In his Twitter response to last week's terrorist attack on a London subway, Trump hinted he might broaden the initial ban.
Facing a mounting legal battle over the policy, Trump signed a pared-down version of the policy in March that left Iraq off the list of banned countries.
