N400 and Canada Visit and Re-entry to US

[bg8]

Hi,

I have applied for Citizenship and in the N-400 i have mentioned that I have travelled to Canada for 3 days. But When I checked my Indian passport I didn't see any US immigration re-entry stamp for the proof for any dates. I guess this is bcos I have travelled to canada in a bus and during the entry to canada and re-entry to US they just asked me my GC. Please let me know whether this is ok. Basically i don't have any proof on my side that i have travelled to canada and that too for only 3 days. Please anyone clarify whether this is ok or do I need any other docs as proof.

Thanks in advance.

Regards,
