It's not wrong but it's risky. Since both of you are meeting for the first time, it would be ideal and safer to meet in a neutral ground other than the person's home. Beside, you can't truly tell who that person is. Most people have different image online and different image in real life. Meeting someone you don't know before for the first time in his place is very risky.

Most people have been taken advantage of through such meeting. What if you don't like the person in life, how would you retreat. If you meeting in an open place like an eatery, you can easily walk away if things fall short of what you expected or he/she tried to take advantage of you. But in his/her place, you can't walk away easily should things fall short of what you expected.

Meeting in a public place for the first time is ideal and safer.

Well in a sane world, there is nothing wrong with visiting an online friend at home for the first time but it's quite unfortunate that we are in an insane world where every stranger has the potential of being a good guy or a rapist, kidnapper or a murderer.

Visiting an online friend at home can be very risky especially if you do not trust the to a large extent. People can be saints online but demons in reality so you've got to be careful with whom you put blind trust in when visiting for the first time.

Furthermore, you have to be prepared for the worst to happen so that you'd not end up being victim to certain social vices.

Conclusively, if you can avoid it, you can meet for the first time in a public place and if you must see the person in his home, go prepared

Definitely it is wrong to visit online friend at home for first time because u dont know who they actually are and also you dont know about their intensions on you. You cant believe someone blindly just by talking through online.

So it is always good to meet your online friend somewere in common place for first time. There are many people who convince by speaking full of lies only when u meet in real you can figure out things more clearly. This world has many fake people its always wrong to trust someone so soon and invite them to home. It will be safer if u meet them up were you can get help.
