I am glad that he has finally decided to actually visit you in Israel.
But what gets me is very simple.....
Why on earth doesn't he do his own research too, instead of relying on you all the time...???
It seems that it is all one-way traffic..... Just you doing all the leg work.
Looks like that he wants to be the prize catch and not vice versa.
If you want to marry him you have to work for it......
Sorry to say, but I don't think that all the responsability for the collation of the various requirements to an eventual visa should be placed entirely on your shoulders.
My two pence worth, for what's worth.....
