If your husband meets the 125% poverty guideline, but does in fact meet the required amount you wouldn't need a co-sponsor. If you were required to use a co-sponsor any U.S. Citizen or Lawful Permanent Resident can sponsor you so long as they meet the guidelines. You will need proof of their status, 3 recent pay stub or letter of employment. Last taxes 1040's and W-2's or schedule C if self employed. Most people include last 3 years taxes although technically it is optional. I recommend 3.
You can have your friend from the remote childhood be your sponsor as well, if he or she qualifies.
