A work permit or work visa is the permission to take a job within a foreign country.
Currently, every EU country has a different process for granting work permits to nationals of non-EU countries. To address this issue, the European Commission began work in 1999 on developing an EU-wide process for the entry of non-EU nationals into the work force. In October 2007, they adopted a proposal to introduce a work permit similar to the United States' "Green Card" program, called the "Blue Card". It is similar to the UK's Highly Skilled Migrant Programme, with the exception that it will require an employment contract in place prior to migration. After two years in the first country, the migrant will be allowed to move and work in another EU country, and can sum the number of years spent in the EU for purposes of residency. This new card will abolish work permits across the EU and centralize the issuing from Brussels. 
The issuing of work permit in the Czech Republic is governed by three basic sources: labor code, Act No. 435/2004 Coll. On employment and Act no. 326/1999 Coll. On the residence of foreign nationals. There are various rights and obligations depending on nationality.
There are seven standard ways to apply for a work permit in the United Kingdom: the Business and Commercial Arrangements, the Training and Work Experience Arrangements, the Sports people and Entertainers Arrangements, Student Internships, GATS, Ancestry Visa and the Sectors Based Scheme. All applications require the work permit holder to leave the country where the work permit was issued every three months under the Work Permit Arrangements. Costs for leaving the airport are £64, per person and you must return to the airport after 24 hours or one working day to leave the country. If you remain in the airport the cost is £35 per person and you must leave the country after 24 hours or one working day in the airport.  Each of these involves its own application process, and generally requires a job offer from a UK employer.
UK Work visas allow for extended visa options which may lead to permanent residence. With Europe at its doorstep and a large domestic market, the various UK work visa categories offer a gateway for thousands of applicants seeking the experience of European life.
The UK work permit system is currently being replaced by a new points-based immigration system.
According to the Federal Migration Service of Russia estimates, Russia's 5 million foreign nationals work today.
In order to work in Russia, foreign citizen must have a work visa (visa for arriving at the order), to obtain a work permit and get on migration registration in the Russian Federal Migration Service bodies.
For foreign citizens arriving without visas (CIS countries except Turkmenistan and Georgia) there is a simplified procedure. The period of temporary stay for them is 90 days but can be extended up to one year from the date of entry into the Russian Federation on presentation of the migration service of the employment contract or a contract of civil-legal nature. That is, a foreigner can obtain a work permit for up to 90 days, and then to extend it after the job. However, it is recommended to immediately impose labor or civil contract and to issue a work permit for the duration of its validity.
Issuance of work permits is carried out taking into account the established quota. The quota is divided by region, Russia and the integrated vocational qualification groups.
A work permit is divided to some categories:
- qualified professionals are employed by their existing profession (specialty), included in the approved list of professions (specialties, positions);
- highly qualified professionals engaged in labor activity in accordance with the provisions of Article 13 of the Federal Law "On the Legal Status of Foreign Citizens in the Russian Federation."
The work permit is valid within the subject of the Russian Federation, in which it was issued.

In general, the United States does not require work permits for adult citizens. However, certain aliens are required to have an Employment Authorization Document from the United States Citizenship and Immigration Services (USCIS) of the Department of Homeland Security (DHS).
The federal government of the United States does not require work permits or proof-of-age certificates for a minor to be employed. However, the possession of an age certificate constitutes a good faith effort to comply with minimum age requirements of the Fair Labor Standards Act of 1938. The United States Department of Labor will issue a "certificate of age" if the minor employee's state does not issue them, or if the minor is requested by his or her employer to provide one. Several states are not listed in 29 C.F.R. 570.9(a), such as Alaska, Arizona, Idaho, Kansas, Mississippi, South Carolina, Texas, and Utah, and thus their certificates may not meet the requirements of 29 C.F.R. 570.5(b) as being evidence of compliance with the Fair Labor Standards Act.
Many states also require them for workers of certain ages. In some states, for example New Jersey, permits are only required for minors 14 and 15 years old, while others such as Massachusetts require, at least in theory, work permits for all minors until they turn 18 years of age. In some states, enforcement is strict. Permits are usually issued through the school system the minor attends, and typically at a minimum is conditioned on enrollment in high school with regular attendance (no chronic absenteeism, tardiness, or truancy). Some states such as New York and Indiana require high school students with part-time jobs to maintain a certain grade point average. Minors who are working are usually restricted in the number of hours each day or week they are permitted to work as well as the types of jobs they may hold.
The immigration in Turkey is regulated by the General Directorate of Immigration Management (Göç İdaresi Genel Müdürlüğü) under the supervision of the Ministry of Interior while work permits are delivered by the General Directorate of Labor Immigration (Uluslararası İşgücü Genel Müdürlüğü) under the supervision of the Ministry of Labour and Social Security (Türkiye Cumhuriyeti Çalışma ve Sosyal Güvenlik Bakanlığı). All applications for both residence permit and work permit are made through online government portals. The residence permit application is made through " "e-Residence" (e-İkamet) while Turkish work permit application are made through e-Government (Turkey) (e-Devlet).
There are three categories of South African work visa or permit available to a foreigner each with its own set of specific requirements all assisting in immigration to South Africa or working in South Africa. These are the General Work Visa/Permit, the Critical Skills Work Visa/Permit and the Intra-Company Transfer Work Visa/Permit. Due to recent immigration law changes (May, 2014), the obtaining of work visas or permits in South Africa has become much more arduous. Furthermore, these work permits are now referred to as visas.
General Work Visa/Permit - The basis of a general work visa/permit is that a firm offer of employment has been made by a prospective employer to a foreigner after such employer has unsuccessfully exploited the local labour market in attempting to procure the needed skills, experiences or qualifications equivalent of such foreigner.
Critical Skills Work Visa/Permit - A critical skills work permit may be issued to a foreigner who possesses critical skills or qualifications and is able to demonstrate with supporting documentation in the form of testimonials, publications. This is based on a list published by the Department of Home Affairs in South Africa called the Critical Skills List  A letter of motivation from an authoritative body to substantiate the benefits that those skills will bring to South Africa. This critical skills work permit is granted for up to five years and may be renewed for a further period, if required. This visa type replaces the previously issued Quota Work Permit and the Exceptional Skills Work Permit.
Intra-Company Transfer Work Visa/Permit - An intra company transfer work permit is issued to a foreigner who is normally deployed or seconded to South African branch, subsidiary or associate office of a corporate entity aboard. There are strict controls to ensure that the foreigner remains employed in his or her specific position during the tour of duty. This type of visa is only valid for two years, and often no extension is possible. Also, any applicant must have first worked for a minimum of 6 months in the employ of the company’s foreign office before applying to relocate and immigrate to the South African branch.
