If you are a student, teacher, or research scholar renewing your F1, M1, or J1 visa and you qualify to submit an application as “interview waived” (IW), mail your documents with DHL as soon as possible. While processing times are delayed, the U.S. Embassy Santiago is still processing IW-qualified ongoing students. When you apply online, if you qualify to apply as an IW based on answers you provide, a “renewal” option will be available to you. Select this option, and you will then receive instructions on how to mail-in your documents to the embassy.
