welcome to this group. I am living 5 min from the border but unfortunately there is restriction against Iranians for getting US visitor visa. Some of us have not met with our spouse for a year . I am happy for you two. I cannot attach a file to this forum but if you leave me your email address I can send you the statistics from Ankara for all the countries.I am from one of those 4 countries. Applied late 2016. I am Canadian citizen sponsoring my wife.
As with all of you, it is hard for us to be apart, but we were able to come up with a solution:
My wife applied for visitor visa to USA, which she fortunately was able to get. We rent an apartment in USA near Canada border, and I travel to see her 2 times a week. If this is a possibility for you guys, you may want to consider this option as well. However, I realize with travel ban in USA this may not be an option for Iranians.
Hope all our cases gets finalized soon.
Did she apply for Canadian visitor visa as well?
