I won green card, my husband couldn't get immigration visa, had health problems and I filed I-130 on 01-26-2012, how long does it take?

You can review the Department of State Visa Bulletin for an overview of recent wait times for priority dates to become current. Most likely you will want to file for naturalization as soon as you are able and that will likely be the fastest route.

It's going to take about 2-3 years before he can immigrate as a spouse of a green card holder because of the visa priority date backlogs.

Current processing time for an I-130 filed by a Permanent Resident for a spouse at the VT Service Center is about 20.5 months.

Vermont Service Center now takes about 22 months to process I-130 petitions of permanent residents for their spouses. In addition, an immigrant visa will not become available to your husband immediately on approval of the I-130 petition because the number of the people who file these petitions is greater that the number of visas that can be issued each year. In December of this year, for example, immigrant visas will be given to the spouses of permanent residents who filed their I-130 petitions in August 2010. So it is reasonable to expect that your husband might receive his green card around May-June 2014.
