My infant (14 months old) is a US citizen with a valid passport. She’s currently in India (with a valid visa) and will be traveling with her grandparents in March (POE - San Francisco). We (parents) will be providing the necessary notarized authorization letter.
Will there be any immigration issue for the grandparents? Will the immigration officer question as to why she is traveling with them and there give less than 6 months of stay?
P.S. Grandparents have a valid US Visa
