Is it really that simple?
Do I need to fill out all the paperwork from the Citizenship and Immigration Canada website?
Can I go to any border?
Do I have to cross the border into another country first?
For example, do I cross into America for a day and then come back and apply then?
Could I just go to the airport and do it there?
1. It is simple, but the hard part is for the employer to get the LMO, unless you have a skill that is in high demand, it probably will be refused.
2, You don't need any paper work until the LMO is approved.
3. It has to be a border point, not an airport, you go the the US side, get a rejection letter (doesn't effect future admissions) and return for the work permit.
