You can e-mail us basic information about yourself with some pictures attached. Before you come we will show this to the lady (or ladies) you are interested in to make sure she (they) will be able to meet with you.
If the date and time for the meeting have been discussed with the lady and fixed, you can't cancel the meeting unless there is a good reason (illness and other Force Major (Force Majeur) circumstances).
This is a very individual issue. In fact, when you talk about where and when a date must take place, you should recollect your experience of a date in your country. The countries may be different in respect of their traditions and history but regarding day-to-day activities and human relationships they are very similar. If this lady is special for you, you can ask for making preliminary reservation at the restaurant, or just decide on a place to go out jointly with the lady. The length of the date is different for different people. As long as you feel excited and comfortable and get the same feedback from the lady, stay where you are:)
Again, this is a matter of personality. There are women who expect to hear a proposal several days after the first date. This also depends on the fact if you had correspondence with her before, how well you know the lady. Other ladies, on the opposite, prefer to get to know the man well, to spend a lot of time with him before getting married. There is no definite answer to this question. Just follow your heart.
