如果你一年前的H1是占名額H1，而從你上一個h1批準日期算起，6年以內，隻要你一直以合法身份呆在美國，如果你再次需要h1工作，這個h1是不占當年名額的。也就是你可以隨時提交h1申請，批準就可以上班，不必要等4月1號遞交和10月1號生效。下麵是我在官方網站找到的相關信息。希望對你有幫助。

請看第四頁的第二段：
When the H-1B category was enacted in 1990, Congress established that a maximum of 65,000 H-1B visas may be issued to aliens during each fiscal year. This limitation, commonly referred to as the"H-1B cap", does not apply to H-1B petitions filed on behalf of aliens who have been counted against the cap in the previous six years and who have not been outside of the United States for one year or longer. Thus, generally, petitions to extend an H-1B nonimmigrant's period of stay, change the conditions of the H-1B nonimmigrant's current employemnt, or request new H-1B employment filed on behalf of H-1B workers already in the United States will not count against the H-1B fiscal year cap.
