hi soft, u can send ur application packet to the universities without gre score card,but they will not consider ur application until they get ur score report.first of all when u send ur application,the university will check their database whether ur score report is with them.if they do not have,they will keep ur application aside.so it is better to send ur application such that it will reach the concern university after 15-17days after ur gre.bec ets people take around 15 days to send ur score card to the universities u have applied.
when u get official score card,u can apply to the additional universities.anyways,best of luck for ur future:tup: .
