In fact, there are some limitations in religious practice in Vietnam. Foreign missionaries are not legally allowed to proselytize or perform religious activities. No other religions than the aforementioned eight are allowed. Preachers and religious associations are prohibited to use religion to propagate ideologies that are opposed to the government. Many Vietnamese preachers who fled for America and other countries say that they were suppressed by the Communist government for no, unreasonable or ethnic reasons; however, preachers and religious associations who abide by the law working in Vietnam today are aided and honored by the government.
