Is the process of conversion of status from H4 to F1 easy and if so is it necessary to get F1 visa as well?

If you are overseas, your then husband is holding H-1B status, and you wish to join him, you would likely do so under an H-4 visa as that is more likely to be approved by a consular officer than an F-1 visa . After being in the U. S., you could make an application to change status to F-1 student. The conversion from H-4 to F-1 status with U.S.C.I.S. in most cases should not be a problem. The question of whether to later obtain an F-1 visa rather than just being satisfied with the F-1 change of status depends upon your need to travel. Both H-4 and F-1 would allow you independence in terms of study options.  For work, you would need the permission of the school for curriculum practical training and of U.S.C.I.S. for optional practical training under F-1, and your husband would have to either have an I-140 petition approved or be eligible for continuation of the H-1B past 6 years for you to obtain work permission from USCIS.
