Hi,
Your application for PR status to Canada will depend on your current residency in the US. If you are an H1/GC holder then you can apply through the common-law partner route through Bufallo I believe.
You can sponsor relatives or family members from abroad if they are:
your spouse, common-law or conjugal partner 16 years of age or older;
your parents or grandparents;
your dependent children, including adopted children;
children under 18 years of age whom you intend to adopt;
your brothers, sisters, nephews, nieces or grandchildren who are orphans; under the age of 18 and not married or in a common-law relationship; or
a relative of any age if you do not have an aunt, uncle or family member from the list above who you could sponsor or who is already a Canadian citizen, Indian or permanent resident.
Common-law partner
You are a common-law partner—either of opposite sex or same-sex—if you have been living with your sponsor in a conjugal relationship for at least one year. The year of living together must be a continuous 12-month period and cannot be intermittent periods that add up to one year. However, you are allowed temporary absences for short periods of time for business travel or family reasons.
You will have to provide documents that prove that you and your common-law partner have combined your affairs and have set up your household together in one home. This could include:
joint bank accounts or credit cards;
joint ownership of a home;
joint residential leases;
joint rental receipts;
joint utilities (electricity, gas, telephone);
joint management of household expenses;
proof of joint purchases, especially for household items; or
correspondence addressed to either person or both people at the same address
What would be my options to go into Canada with her?
Do you mean before your PR application or after? If it is before, assuming you are a Brit ppt holder then you can visit for a validity period of 6 months (but this would be under the discretion of the Immigration officer at the point of entry if he/she is convinced of your intentions to return to the US or UK after the period of visit).
Hope this makes sense! Check
www.cic.gc.ca for more info and others can clarify if I am not right.
Good luck!
