further evidence of relationship as spouses

Hello,

Recently I was interviewed in Buffalo, but the VO did not make final decision on my application for PR under spousal sponsorship, and required additional further evidence of our relationship as spouses, especially after the marriage. But We did all our best, and provided her all required documents, proofs listed on the checklist and guidelines.

My situation is that I am living in the US legally as an international student, doing my master degree, and I loved and married with Cuban who has PR in Canada, and almost we have married more than a year. We have decided to live together in Canada after my graduation. She lives in Canada with my grandmother now. By the way, I have relatives there. Due to my full time study, We are living apart, but I did a lot of travels to live with her even for the short times, almost every month I did. She cannot come to live with me, because of Cuba Citizen, tried to apply for US visa, but was unsuccessful. So I did all travels to Canada. And always We almost every day kept in touch with phone, skypein call, mail, chats when we were apart and every visit, We tried to make more proofs like photos, receipts etc. For information, We also have proofs till the marriage like photos, bills, chats, photos from wedding ceremony etc.

I am trying to explain briefly my situation; now my concern is what will be your suggestion and comments in this case. VO asked me that give me some proofs that show your further evidence of your relationship as spouses, like joint bank accounts, insurance, something that connects both of you. But in my situation, We are not capable to provide like this documents because I live in US, She live in Canada, both have separate account, separate insurance now, of course we will have joint account, insurance, rent when we live together soon.

I will appreciate that please feed me back if you have any idea, experience on this case. What kind of evidence we can provide? And What will be the final of the process, because VO give me two months. After two month, she said If I could not provide sufficient evidence, she would reject the application .

Thanks in advance.
