A visa allows the legal entry into and sojourn in a foreign country under the conditions of the visa, which may vary according to the type of visa. Furthermore, it confirms the validity of the passport and its legal status through its issue by the foreign government. A visa is perceived in some countries as a “confirmation of permission to enter the country”, and in other countries as a “recommendation of the consulate to enter the country”. The United States, Japan and Korea perceive the issue of a visa as a “recommendation of the consulate”.Accordingly, even if a foreigner who wishes to enter Korea and is in possession of a valid visa, he or she might get rejected by an official at the immigration if the person does not meet certain entry requirements — for example, in case of prohibited entry, attempting illegal employment, or having no specific reason for entry, etc.The right to issue a visa is in the hands of the Ministry of Justice. But it can be transferred also to the heads of other government institutions such as embassies, government agencies, consulates, and consular offices
