International students are students, usually in early adulthood, who study in foreign educational institutions. The word student is etymologically derived through Middle English from the Latin second-type conjugation Verb "studēre" Types of educational institution include Higher education College Career college While most universities have official student exchange programs, some well-funded high schools have them, too. A university is an institution of Higher education and Research, which grants Academic degrees in a variety of subjects A student exchange program is a program in which a Student, typically in secondary or Higher education, chooses to live in a foreign country to learn High school is the name used in some parts of the world (in particular Scotland, North America and Australia) to describe an institution Although some students travel abroad mainly to improve their language skills, others travel to advance their specialized studies. Still others study abroad because suitable tertiary education is either in short supply or unavailable altogether in their home countries. In addition, in many parts of the world, a foreign degree, especially if earned from certain countries, is honored more than a local one.
Prospective international students are usually required to sit for language tests, such as IELTS & TOEFL(English speaking education), DELF (French speaking education) or DELE (Spanish speaking education), before they are admitted. IELTS (pronounced /'aıelts/ stands for International English Language Testing System The Test of English as a Foreign Language (or TOEFLs, pronounced "toe-full" or sometimes "toy-ful" evaluates the potential success of an individual to use The Diploma in French Studies (known in French as the Diplôme d'études en langue française) is a certification of French-language abilities for non-native The Diplomas de Español como Lengua Extranjera (DELE ( in English: Diplomas of Spanish as a Foreign Language) are official diplomas issued by the Spanish Instituto Tests notwithstanding, while some international students already possess an excellent command of the local language upon arrival, some find their language ability, considered excellent domestically, inadequate for the purpose of understanding lectures, and/or of conveying oneself fluently in rapid conversations.
Many countries force international students to pay higher tuition than citizens of the country. This discrimination is usually justified by the argument that the students' parents do not pay taxes in the country. The fact that a large number of international students decide to settle in the country where they are studying and become productive citizens is, however, ignored in such cases.

International student programs can be a politically sensitive issue in the host countries. Opponents of the programs fear that international students would take the limited university placements away from local students. Proponents of the programs counter this belief by arguing that the high fees paid by international students enable universities to maintain, or even increase, placements for local students.
It is not unusual for international students to encounter language problems in the host countries. Despite the pre-admission language tests — which might give the students a false sense of mastery over a foreign language — students often find it difficult to understand the coursework, and some might feel that their lecturers are unhelpful in explaining the coursework to them. Academics, under pressure from cash-strapped university authorities to retain international students, sometimes make the courses easier, to the resentment of many local students. It has been speculated that language difficulties may contribute to the problem of plagiarism, particularly in the form of using essay mills. Plagiarism is the unauthorized use or close imitation of the language and thoughts of another author and the representation of them as one's own original work An essay mill, sometimes also called a paper mill, is the colloquial term for a type of Ghostwriting service which specializes in the sale of Essays term 
Finally, many would-be employers, especially those within the host countries, find some former international students have unsatisfactory language abilities, despite having earned university degrees.
A major drawback of International Students Programs is the reluctance of universities, in the host country, to face immigration limitations and expose them clearly to their incoming foreign students.
