Dear Customer (name blocked for privacy),
For future information, if you surrender a green card, then you have to start all over again. If you do not surrender it,and simply do not return to the us for a time, you have conditions and a chance to allow you to come back into the country as a returning resident. If someone adviced any of your family to surrender the green card, it was not the best advice they could have received. The damage is done now.
Surrendering a green card does not diminish your potential to get a new green card. It is just that you have to go through the process again.
When you say renewal, I need to know what you mean. The langauage is not translating here.
If the brother is sponsoring her, and he surrendered his green card, then he can not sponsor her for a green card, because he is no longer a permanent resident.
If she is applying for re-entery as a returning resident, it has no effect.
YOUR PAYMENT AND BONUS IF ANY MAY BE TAX DEDUCTIBLE
