My parents got LPR in Feb 2007 and arrived in May 2007 were here for 4 months and applied for rentry permit in Aug 2007 and then left to india. Permit came in 2008 and was valid till 2010, april, 10. Now they arrived back on April 2 2010 and now I am applying for another 2 years rentry permit. They both have got operated for knee surgery in india and need ongoing physical therapy from the hospital that did the surgery plus other medical conditions. My question is will there be any problem in getting the rentry permit again second time now ? Also, last time when they applied there was no appointment for finger prints for the I-131 but I dont know if they will need one this time ? Do you need FP for LPR rebtry permits ?
