My company collected the documents and required information on 20th Jan and started processing my L1B blanket visa. How much time it will take for petition and what will be next step towards stamping? Probably what is expected date of Visa interview?
Once they file the petition w/ USCIS, it can take 2-6 months. If RFE is issued, then it will take longer depending upon how much time employer takes to respond to the RFE. Once approved, you can look up for next available dates for visa interview and attend the same. If visa stamp is approved, then you are all set. If they put the visa under administrative processing then it can take few weeks to several months to process.
