Hi All I've got an appointment for my visa interview. I'm confused seeing all the postings I'm currently working in IBM Bangalore, i've got just 3+ years of realtime experience in this field. I've completed my Bachelore of Computer Applications and then Master of Information Systems....and with good percentages... I've seen many posting who's visa got rejected even for 4+years of IT experience VO's asking for 6+ years of exp. I'm afraid...is my exp and background sufficient to get throug the interview and get visa stamped. I'ld be more happy if you can help me in this reg. waiting for reply Smitha
