Thanks, Mytwocents and xiaobaitu, But,

I am still confused. Please read the following I copy it from uscis.gov

How Do My Spouse and Child Apply to Extend Their Stay in the United States?
If your employer files USCIS Form I-129 (Petition for Alien Worker) for you, then your spouse and child must carefully read and complete USCIS Form I-539 (Application to Extend/Change Nonimmigrant Status) and submit any required supporting documents to extend their stay. It is best to submit both forms at the same time.

If you are filing USCIS Form I-539 for your own extension, you may include your spouse and any unmarried children under the age of 21 in your application if you are all in the same nonimmigrant category. You may also include your spouse or children in your application if they were given derivative nonimmigrant status. This means that your spouse and children were given nonimmigrant visas based on your nonimmigrant status. For instance, if a student is given an F-1 "Academic Student" visa, then the spouse and child are given F-2 "Spouse and Child of an Academic Student" visas.
