Question Detail:

As Salaamualuikum
Is it Sunnah to visit someone that has come from Hajj or Umrah?

Answer :

In the Name of Allah, the Most Gracious, the Most Merciful.
As-salāmu ‘alaykum wa-rahmatullāhi wa-barakātuh.
It is encouraged to honour a person who has returned from Hajj by visiting him and requesting him to make dua.
Consider the following Hadith,
إذا لقيتَ الحاجَّ فسلمْ عليه وصافحْه، ومرْه أن يستغفر لك، قبل أن يدخل بيته، فإنه مغفور له  قال رسول الله -صلي الله عليه وسلم -: 
When you meet a haji, (upon his arrival) greet him and shake his hands and request him to make istighfaar(dua) for you, before he enters his house, for verily he is a forgiven one. (Musnad Ahmad)¹
The above Hadith is specific to a Haji. However, a person who has performed Umrah is also worthy of honour.
And Allah Ta’āla Knows Best
