april?? h4 to h1

[guest1978]

My wife is trying to switch from h4 to h1 visa, and most employers are asking her to contact them in April. is it just a 6 month time period they consider a cushion, or is it of any significance from a immigration view point?

thanks to all the gurus

CIS starts accepting new H1 application in every April. That is why.
