Hello! I am expecting my boyfriend to arrive very soon. He has approved Eta form but i am worried because he is planning to stay with me 180 days and i know that that is the maximum .However, I am worried that an immigration officer may find it susposios (the leinght of his stay) and may refuse his entry in Canada when he arrives . He has been im US few times (for work) but the stamps for his visas. Are in his privious pasport and i dont know if the immigration officer will be able to see that he traveled before and left the counry on time) please share some. Similar experiance or ideas.
