you should be happy that you are using what ALLAH SWT has given you ,and yes if it would take for the both of you to succeed in life,love and hereafter to embrace Islam and endure your relation for ever inshallah you must think about it.
as for papers etc..,from my own experience ,my marriage with a western moroccan girl never happened due to her lies and I THANK ALLAH SWT that this never happened ,of cource it takes time to realise it.
as for papers ,visa as you see North African men is threatened targeted even by his own sisters..
i bet it is a good faith and destiny you have taken the extra mile and have used your good faith and spirit to love this man "hisham"despite all what plp say.
i have to say ..go for it but use your mind and don't hide your worries from hisham,better now than later ..
sometimes your soul-mate may be from another world
