The growth and development of human societies in all areas has prompted most countries to open their borders to foreign immigrants in compliance with the country's internal laws and regulations. Immigrating to foreign countries is one of the most common ways to live in another country. Of course, currently, many people in the world want to travel to one of the foreign countries to improve their living standards or their education and business. Many countries have been included in the list of countries that accept immigrants in the world and in this regard, they have also allocated significant statistics.
Globally, there are 230 million immigrants, which constitute about 3% of the world's population. These figures have not changed in the last year because the world population has increased in the same direction. The number of countries accepting immigrants has increased from 50 countries to more than 200 countries since the early 1900s. These factors indicate that more borders have been opened to accept immigrants.
