I have a stamped h4 which is valid for another 3 years. Last October (2009) I started to work for an employer that did my H1 (part time). I have that H1 approval but it is not stamped. In June (2010) the same employer converted me to a full time and has filed an amendment to the par time H1. The amendment petition is still under process. I know I need to get H1 stamped. Can I use the part time approval for the stamping or do I need the new amendment approval? I am leaving for India in 3 weeks. If the new one is required then I will have to go in for PP. Thanks in advance for your assistance.
