What job do you have that fllas under skilled worker, and do you have a sponcer for that permit?
It's not a work permit, it's an immigration application. He doesn't need a sponsor.
AP, here are some suggestions:
1. Make sure to read and re-read your IMM0008 so that everything is perfect. Make sure dates are correct, facts are correct, etc.
2.
Cross-check all of your schedule 1 information with all of your personal documents - degrees, certificates, schools, jobs, etc. Then cross-check that further with your addresses. This is the place I think most people make a mistake. Make sure everything makes sense - like if you claimed to be working in Missouri, but recorded your address for that time as Nevada, etc.
3. Your schedule 1 history should be recorded month-to-month, with no gaps whatsoever. Fill-in gaps with "unemployed," or "student," etc.
4. Make sure to include as much as you can to substantiate your work history (copies of pay stubs, job description, letters from supervisors, etc.)
Keep in mind that the better documented your application is, the less likelihood you will have of needing an interview. And an interview will add maybe 6 months or more to processing time.
Good luck.
