Hi
I have stamped my H1b Visa in 2008 after that i went to embassy for B1 Visa stamping.there it asked me why you didn't went on H1b Visa i told them due to recession my employer didn't turned me up.so that's the reason for not travelling on H1b.At that time consultate has written CWOP on my H1B Visa and issued me B1 visa.
I donot know what exactly CWOP means.Later my employer is calling me on H1B Visa.
I have planned my trip for US but on delhi airport at immigration they refused to go to US as CWOP is written on my H1b Visa.they told me to check with embassy people and verify about ur visa

Please help me what should be done in this case as my petition is valid till 2011 but my visa is CWOP
it means my visa is cancelled and i have to reapply for H1B Cap or i have to give H1b Interview again.Please help me out
