Put in a nutshell, Marlyn, and the boss as well, each make very valid points in their respective responses. Given the intricacies of the UK Visa System, it would be far less complicated overall if your boyfriend were to visit the Phils.It's what I, myself, did (after also meeting my then girlfriend online) ... and, it would be fair to say, [most] other men did too ... because this factor on its own, demonstrates a certain level of commitment on the man's part - which is invaluable if and when a couple decide to "tie the knot" and apply for one or either of the settlement visas. Likewise, photographic evidence of the two of you together is vitally important in this context.
Good Luck with your 'powers of persuasion' to this end ... and
