Hi Kimmi!
Did u mean you got engaged already without meeting him yet personally? or accept his marriage proposal thru internet after chatting with him for at least 3 months? i don't mean to be negative but i think it's better to meet him in person first. u can see some of his attitudes that u don't know thru chat like the way he react to things, etc... marriage is a very serious thing so it's better to know him better first. anyway sometimes love happens like a roller coaster so if you're already sure & when u apply for fiancee visa, i think it's better to state in the application form that you got engaged after he visited you. If he was really sincere, he should be the one who suggested to visit you and not you visiting him first. you know, filipina values....it's just a piece of advice & it's up to you. Good luck!
