How long do you mean when you say "extended"? A US citizen can enter Canada for 6 months at a time, to review, they simply need to leave and return for another 6 months.

Can you get a job in Canada?

The customers officer can actually force you to return at any time, but the law says you can stay for a maximum of 6 month. That being said, you must return and come back.

If you schedule a firm exit at the end of 6 months, they are more willing to let you stay. You can also show that you have firm committments that are important during that time to show that you have every intention to return.

For example a job obligation, family obligations etc. - weddings, big projects, intended travels.

You are very welcome, does that answer your questions today?

If you get married you may be able to get sponsored. If you want to apply for PR directly, you will need work experience in specific fields, likely a federal killed worker program or skilled trade program.

If you can get a job in Canada, you can do the Canadian experience class through express entry.
