We are sponsoring my husband's mother from Latvia. Visa is ready and sitting in Warsaw, Poland. She is an elderly lady and not able to travel to Warsaw to pick it up. She has only options (suggested by Warsaw office) to use courier service by UPS, TNT or by DHL (not FedEX). Does anyone had this experience? We can't do it on-line. DHL requested cash only payment to be payed in Warsaw(ha-ha-ha).Please help.
