Is visa required for I512 holder
 

If a person is in process of receiving GC, and he is currently in posession of I512 card (combo advanced parole and work authorization).
Does this person fit into:
persons lawfully admitted to the United States for permanent residence
who are in possession of their alien registration card (Green card) or
can provide other evidence of permanent residence;

ie, can travel without visa to canada? Ive tried to call multiple consulates in US - none of them answer phones for visa questions. Email'ed them as well - got back vague answers...

I guess there are two places the trip may come to stop - airline desk if they decide i512 is not sufficient proof for entrance to canada, and then border patrol...

anyone had experience or thoughts about this?

thanks!

Depends on your nationality/passport. You do not have the GC yet, so will probably need the visa.

Check www.cic.gc.ca for details on which countries' nationals require a TRV

When is Advance Parole Required For Travel?

Q: Do I need advance parole to travel if I am here on a non-immigrant visa and have applied to adjust my status to Legal Permanent Resident?

A: For most visa categories, you need advance parole from U.S. Citizenship and Immigration Services (USCIS) to travel internationally if you have applied to become a legal permanent resident (LPR). Failure to obtain advance parole BEFORE departing the U.S. effectively invalidates your LPR application. It is not enough to have applied for advance parole; you must have received approval before you travel.

There are three exceptions to the requirement for non-immigrant visa holders to apply for advance parole. Those here in H1B, L and K3/4 status - and their dependents - do not require advance parole to travel after applying to adjust their status. K1/2 visa holders who have married a U.S. citizen must apply for LPR status and advance parole prior to international travel.

NOTE: USCIS now issues employment and travel authorization on a single card for certain applicants filing an Application to Register Permanent Residence or Adjust Status, Form I-485. The card looks similar to the current Employment Authorization Document (EAD) but will include text that reads, "Serves as I-512 Advance Parole." A card with this text will serve as both an employment authorization and Advance Parole document.

thanks, but i512 is the AP, so we already have it. Question was - is it sufficient for Canada Border Patrol, or visa is required.
All indications are for the latter.
