Sevis

[RAJ]

Hi all...

I have my student F1 visa till 2015 but sevis is completed due to OPT denail but got new I-20 from same old university for different academic program. Now while re entering the US from India to have new sevis activated do I again have to go to visa interview with new I-20 or with same old visa and new semis can I re enter ?
Please let me know... Now am in India when can I pay my sevis fee? How many days before I re enter?

No need of visa stamping. just pay ur sevis fee when u get ur new sevis number. Usually it takes 48hrs to get active
