just got married US citizen how can I bring my wife and step kids over to the US

You will need to file an immigrant visa petition on behalf of each family member to start the process. You can petition for a stepchild so long as he/she was under 18 years of age at the time of the marriage. Once the petitions are approved, your family members will apply for immigrant visas. The process typically takes 12 to 18 months. An attorney can often speed up the process by making sure firms and supporting documents are properly filed.
