A Work Visa is essentially a work permit that allows you to enter a foreign country and legally work there for a certain period of time.
Different countries have different eligibility requirements and procedures for a Work Permit.
Some countries require you to have a job offer in the country before you can apply for a Work Visa. You are also required to be sponsored by the Company which has given you the job offer.
Some countries allow you to enter on a Tourist or Business Visa. You may then apply for a Work Visa once you have obtained a job offer in the country.
Again, there are certain countries which allow you to apply for a Job-Seeker Visa. You may enter the country on this and then apply for a Work Visa once you get a job offer.
Thus, it is not possible to point out the countries where it is “easy” to get a Work Visa.
The ease of getting a Work Visa depends on a number of conditions like the country, eligibility requirements etc.
If you meet all the eligibility requirements of the Work Visa of a particular country, then you may be able to obtain a Work Visa.
