I came to visit my family. My son in-law mother suffered an accident on January, 2013. She was in the hospital in intensive care. He and my daughter are helping to take care of her at her home while she recovers. I will like to support my family during her recovery process, helping my family to watch my granddaughter who is 1 year old, while her parents support her grandmother . I will like to know if it is valid to ask for an extension to stay for those reasons.
