This chart represents the percentage of graduates planning on staying in US as opposed to returning to their country of origin.The countries’ percentage of doctoral grads that plan to stay in US are mostly from China, India, Iran, Nepal. The highest percentage of graduates from foreign countries planning to stay are mostly from east and south Asia of 79.2%. Consequences are that the countries of origin lack people with high skills; e.g. many doctors and nurses in Jamaica left to gain a higher wage/salary which is beneficial to the host country but not so much for the country of origin.
