@AnnaMBoros, I'm just going to assume the child is not related to you or your husband. How old is this child?
This applies to trying to bring an adopted child over - assuming you are NOT considered habitually resident in the U.S. That's another can of worms.

"An adopted child if the child was adopted before age 16 (or before their 18th birthday, if certain circumstances described on the Adoption-Based Family Petition Process or Adoption-Based Form I-130 Process page apply), AND the adoptive parent has satisfied 2-year legal custody and joint residence requirements. (The legal custody and joint residence do not have to be during the same time period, but each must be met for a cumulative 2-year period.) NOTE: Most adoption-based immigration occurs through the orphan or Hague processes. If you are considering pursuing the Adoption-Based Form I-130 Process, you should review certain eligibility considerations. See the Adoption pages for more information."
