Are all employers required to pay half (7.65%) of FICA taxes?

I received a W2 from a large international organization, the World Bank, that does not withhold taxes for its employees. I was told I have to pay the full 15.3% of FICA taxes on my own. Is it possible that some organizations do not pay half of their employee's FICA taxes? If so, how do I report this on Turbotax to make sure my full share of FICA is being calculated?

 

Thanks for your help
