There are three different types of sponsorship:
1. Family sponsorship - if she is your wife, then you can sponsor her for residence;
2. Employment sponsorship - if she is your employee, then you can sponsor her for residene; or
3. Financial sponsorship - if she needs to prove that she will not become a "public charge" as part of a nonimmigrant visa application, you can provide an affidavit of support for her.
We can help you determine which of these makes sense in your situation. Feel free to call us to schedule your free initial consultation.
