Such a regulation would dramatically change US immigration law and could conflict with domestic law and longstanding international commitments.
The draft regulation was described to CNN at a very early stage and has not yet been submitted to the White House for review. If implemented, it would likely result in immediate legal problems for asylum seekers and lawyers.
A Justice Department spokesman declined to comment.
The current law allows migrants to apply for asylum at any legal port of entry into the US, as well as between valid ports of entry, where the passage to the US is illegal.
Yet Another Part of the bill gives Attorney General Jeff Sessions the leeway to regulate which offenses are "considered crimes," in which case asylum is unavailable.
How exactly is the rule tailored and whether it contains exceptions? Re
But there are also international treaty obligations that require the US to treat asylum seekers in a way that respects international human rights and refugee protection, including non-implementation their ability to apply for asylum.
However, there is a part of the law that describes asylum as a margin of discretion – something the sessions has already signaled to expand in recent months.
Reflections on such an asylum-limitation plan are in line with the views of many Trump officials who, given the fierce backlash against the separation of migrant families at the southwestern border, have emphasized that asylum-seekers should go to valid immigration  "We have a legitimate system to enter the country as a family and it is not a crime to enter the land at the ports of entry," Sessions said Monday in Nevada.
"We talk about driveways into the deserts, remote areas, dangerous areas, people bringing children," he added. "That should not be like in the United States."
Some experts say that burdening an asylum seeker – especially because many of them have no access to a lawyer and are not granted by the government – could be prohibitive for many.
Sessions has broad power
As Attorney General, Sessions has extensive legal authority over asylum procedures.
Not only is the government of the home country unable or unwilling to help the victims, he said, but also "the claimant must show that the government has tolerated private actions or proven inability to sacrifice to protect."
