I am an Indian National working in US on H1B visa. My current employer has asked me to consider an opportunity to travel and work at a client office for 17 weeks in Lagos. Visa on my passport has expired and if i consider this opportunity i wish to appear for a visa interview in Lagos to stamp my h1b visa. Since I am not a Nigerian citizen, is it ok to attend for a visa interview in Lagos or is it better to go to my home country for visa stamping? Please advise. (all my previous visa stamping were in my home country)
