(CNN) Republicans are circulating a draft immigration bill that would overhaul the country's legal immigration system, boost border security, overturn rules that govern family separation at the border and provide a path to citizenship for recipients of the Deferred Action for Childhood Arrivals.

The draft bill, which was born out of weeks of behind-the-scenes negotiations among moderates, conservatives and House leadership, represents the most concrete step yet House Republicans have taken to tackle immigration even as the party faces long odds for the bill ever becoming law.

The bill, which reflects President Donald Trump's desire to address "four pillars" of immigration, includes $25 billion for border security including the President's wall, an end to the diversity visa lottery, cuts to family-based visas and a path to citizenship for DACA recipients through a program that would be a merit-based point system and would allow other immigrants to attain permanent status alongside DACA recipients. The cut visas would be reallocated to accommodate the new green card system and more employment-based visas.

Still unknown is whether the bill, which was enough to keep moderates from moving ahead with their rebellion to push for votes on other four other pieces of immigration legislation, will have enough support in the Republican conference to pass. Moderates made major concessions in the legislation, but members of the House Freedom Caucus and the Republican Study Committee, two top conservative groups in the conference, haven't said where they stand yet.

Rep. Mark Walker, who chairs the conservative Republican Study Committee and has been helping to negotiate, said he still needs to read the bill to decide on his vote.
