The two lawmakers aim to collect 218 signatures to bring the bill to a vote without the approval of Republican leaders.
If passed and signed into law, the legislation would restore Temporary Protected Status (TPS) for eligible Afghans, allowing them to remain in the United States until July 2029.
The Trump administration revoked TPS for Afghan refugees who were evacuated to the United States following the fall of Kabul and has taken steps to deport them. However, several federal courts have blocked the deportation of Afghan refugees to Afghanistan and Pakistan.
Crow and Liccardo need the support of all current Democratic representatives and several Republicans to secure the required signatures. If at least 218 lawmakers sign their petition, they can force Republican House leaders to hold a vote.
The two representatives had taken an initial procedural step on 1 October, allowing them to begin collecting signatures immediately after submitting the new petition.
Their bill, introduced this summer, requires a majority vote in the House of Representatives to pass.
Jason Crow, a US military veteran who served in Afghanistan, said Afghans who worked alongside American forces had risked their lives to protect US service members.
He said he was working to bring legislation protecting Afghans living in the US to a vote because he would not allow his country to abandon those brave Afghans.
Sam Liccardo also said thousands of Afghans had risked their lives alongside US forces because the US had promised not to leave them behind.
He warned that they now faced the risk of being returned to Taliban rule.
Liccardo stressed that action on the issue should not be delayed until Democrats regain a majority in the House of Representatives.
So far, four Republican lawmakers have supported the legislation: Don Bacon of Nebraska, Maria Elvira Salazar of Florida, Joe Wilson of South Carolina and Morgan Luttrell of Texas.
Kevin Kiley, a representative from California who was previously a Republican and now serves as an independent, has also backed the proposal.
More than 50 organisations, including Iraq and Afghanistan Veterans of America, Veterans of Foreign Wars and Amnesty International USA, have expressed support for the legislation.
The US Congress established the TPS programme in 1990 to allow migrants who cannot safely return to their home countries because of war or crises to remain and work in the United States for a designated period. This protection can be extended.
The Biden administration extended these protections to Afghans in 2022, but the Trump administration announced in May 2025 that it would terminate them.
Kristi Noem, who was serving as US Secretary of Homeland Security at the time, said the programme had been created to provide temporary protection to migrants and should remain temporary.
She claimed that security conditions in Afghanistan had improved, its economy had stabilised and Afghan nationals could return to their country.
