How many years can I immigrate with a monthly salary of 5000?

Skilled migration-with your current conditions, the success rate is about 0%

Investment immigration-assets of at least 200W and detailed investment plan (English version)

With an English score of 80 in junior high school, I don't think I can even write a complete investment plan.

If you are 30+, stay at home.

20-30, it is recommended to apply for language+junior college first, generally 1+2 years, and get a work visa after graduation. After working in the local area for 1-3 years, you can apply for skilled migration. This is the only way.
