My wife just received her permanent residence (with 2-yr. condition) in Feb. 2017. I will be taking a 2-yr. job overseas. We are filing an I-131 reentry permit requesting 2 years. I've been informed to do this at least 2 months prior to our departure to allow for her (2nd) biometrics appt.. So that I time this correctly, I need to know if the reentry permit clock starts when they process the form or when we stated our departure date of July 1. My aim is to avoid her needing to return a month or so prior to me to prevent violating the 2-yr. limitation.
