Hello,
Please I am inquiring about my moms non immigrant visa renewal. She was granted a 2 years visa that was suppose to expire on September of 2018. Since we want her to visit the US by July of 2018, we sent her passport to the US embassy Abuja for visa renewal, though, through the drop box. On picking up the passport from the UPS Dropbox office, we noticed that the original visa on the passport was cancelled with the inscription ''CANCELLED WITHOUT PREJUDICE" and there were no other issued visa on the passport nor a correspondence stating why the visa was cancelled. Please advise, should we re-apply for a visa interview?
