I have 32 hours per week part-time H-1, I am working full-time for the same job title soon. How much time and fee does this H-1 amendment cost?
-Only need to pay the I-140 filing fee of $580. But I don't think you need to file the I-140 amendment because 32hrs/week is not big different from a full-time (35-40hrs/week). So, you may just extend your H1 at full-time level in the near future before this part-time H1 expires.
