Hi Rex845,
I would like you to know that we are in the same situation and i know this is pretty much stressful for you and your partner. Let me share you my story. I hope you can learn something from my own experience
I am a Canadian citizen and my partner is a transgender woman from the Philippines. I met her on a dating site last Jan 2014. After one year, Jan 2015 - i visited her country for 2 months (first meetng). Same sex is not permitted in the Philippines and her country still recognize her gender at birth. We had Holy Union in the Philippines which was attended by her family, relatives and friends.
Heres the list of what i have accomplish during my first visit.
Skype and email conversation
Western union (from day one to present)
We bought Property in US under our names
Forex cargo boxes and flower delivery receipt (i sent her some items from Canada like chocolates, gifts, etc)
Holy union ceremony
Tons of Pictures
Post mailed letters
Travel abroad and local travel (boarding passes, hotel accomodation)
Conselling certificates (for married couple) signed by reputable Psychologist
Visited chosen orpanage (we have acknowledgement letter from them under our names)
We open a joint bank account
Wills (health will, power of attorney and last will and testament)
Insurance naming her as my beneficiary
Mid of 2015, She was rejected trv in Canada. She own a property in the Philippines, have job and decent amount of money on her own bank account. I gave all necessary documents like invitation letter, we disclose that we are in a relationship. My advice is be honest. If you choose to say that you are "just friends", its concealing of truth. if you later decide to apply as conjugal you will be in deep trouble. The VO will automatically deny your conjugal app and may subject for fraud. Its legit to say that you are in relationship and he wants to visit you, if he get denied then you have 1 proof of immigration barrier thus you will have greater chance of conjugal app.
After the trv rejection in Canada, we wanted to visit NYC and hoping to get married while on tour but she was also denied a visitors visa in the States. I firmly believe that it is a Human Rights to marry someone we love and since she was dnied to enter only proves that we exhaust all possible means for us to get married but was denied due to immigration barrier. Its another evidence for us to show to CIC.
Jan 2016 is my second visit to the Philippines to be with my partner and will most probaby stay here for 3 months.
Heres so far of of what we have accomplished in addition above
Spent holidays the Philippines together with her family
Visited chosen charity orphanage for second time
Diamond ring receipt
Purchase item receipts and dine inns (from 1st and 2nd visit)
Statutory declaration from family, relatives and friends attesting the relationship is genuine and continuing
Additional pictures
Another travel outside the country including local travel (visited another country for 2nd time)
Vehicle purchased
Affidavit from insurance attorney stating that she cant list me as her beneficiary in her life insurance.
Now, take a deep breath. Gather as many evidence as possible, prove that conjugal is best route for both of you. Dont limit your self in gathering documents, remember its a case to case basis. Be creative and just enjoy the moment. Travel together as much as possible and keep boardng passes ticket receipt, etc. Dont worry about applying for conjugal eventually it will come, concentrate on evidence that you will present.
Based on my understanding in your case, most likely he will get denied if he applies a trv. Canada does not have fiancee visa and he is high risk of over staying because you have relationship. CIC may think that you will get married and apply inland spouse sponsorship. But thats ok. If he gets denied that means you have solid proof for both of you that you can present along with all evidences you have.
You cannot jump to conjugal until your partner gets denied by a visa. Do it one at a time, trv first, then gather all evidences you need, then you can think of conjugal.
Stay positive and good luck.
