On June 4, the Alabama legislature passed SB 148. It moves the petition deadline for independent presidential candidates from September 6, to 82 days before the general election. In 2016, that would be August 18.
The bill also moves the deadline for presidential primary candidates to file their petitions from 90 days before the presidential primary, to 116 days before the presidential primary. Presidential primary candidates need 500 signatures (or, if they wish to get 50 signatures from each U.S. House district, then they only need 350). The 2016 presidential primary will be on March 1, so presidential primary petitions will now due in December 2015, assuming the Governor signs the bill.
