I want to live abroad, can I apply for a work visa to go abroad first, then renew it, and finally successfully immigrate? If so, how to do it?

Your idea is quite right. First of all, you should find a foreign company to hire you and ask them to submit a job application for you. If the application is successful, you can apply for a work visa or apply for a visa at the consulate. The duration of a work visa is different in different countries. After the work visa expires, if you do a good job, the company that hired you will generally extend it for you. When you get a work visa to work abroad, you should ask the company that hired you and ask them to handle skilled migration for you. This is very important. To apply for skilled migration, the company that hired you must agree, and they will submit an immigration application for you. This is the basic step, and there are many details in it. You can only go step by step, there is no shortcut. Wish you success!
