Actually, the only immigration legislation that will be considered by the US Senate as currently constituted is omnibus ("comprehensive") immigration legislation. It will address several guest worker programs, amnesty for unauthorized migrants, border enforcement, personnel issues at CIS and Border Patrol, fees and budget authority, naturalization,and more. The leadership of the senate chose that strategy in order to require tech company management and others to lobby in favor of a bill with both benefits for them -- like driving down tech wages -- and other changes that are unpopular with the public -- like amnesty. It's a gambit they use to get both sets of changes through instead of only the popular or best funded ones.
