I have posted in regards to bringing my mother-in-law here from Iraq on a green card via her daughter (my wife). My mother-in-law came through an IR-5 visa, which is for a parent of a US citizen who is at least 21 years old (again my wife).
She has been with us since June of this year and plans to head back to Iraq in November. Do we need to inform anyone or fill out any forms that she will be leaving the US for the time being? Someone mentioned I had to fill out a notice form but cannot find anything about it.
