Eligibility
   To petition for your relatives to live in the United States as green card holders, you must be a U.S. citizen or a permanent resident.    

   After Filing Your Petition
   You will be notified by USCIS if your Form I-130 petition is approved or denied. If it is approved and your relative is outside the United States, he or she will be notified to go to the local U.S. consulate to complete visa processing.      
   If your relative is currently in the United States, he or she may be eligible to file Form I-485, Application to Register Permanent Residence or to Adjust Status, at the same time as you file Form I-130.    

   Employment Authorization (Work Permit)
   Your relatives do not need to apply for employment authorization (work permit) once they are admitted as an immigrant with their immigrant visa. If your relatives are now outside the United States, they will receive a passport stamp upon arrival in the United States. This stamp will prove that they are allowed to work in the United States until their Permanent Resident Card is received.      
   If your relatives are in the United States and have applied to adjust to permanent resident status by filing Form I-485, they are eligible to apply for employment and travel authorization while their case is pending. Your relatives should use Form I-765, Application for Employment Authorization and Form I-131, Application for Travel Document, to apply for travel authorization. The fee for Form I-485 also covers Form I-765 and Form I-131 until a decision is made on the application to adjust status.    
   Note: If your relatives has spouse or minor children abroad, those children and the spouse may be sponsored on the same petition.
