Question Summary:
Can my parents visit me and stay at my home for a long period of time?

Question Detail:

I live with my husband and  daughters. My elder brother and my elder sister also lives near us. My parents live in India and visit us occasionally. My in laws also live in India. They too visit us occasionally.
My question is, in Islam, is their any ruling that a father or mother cannot visit their married daughter's house for a long period of time say 3 months or 6 months or a year) ?
Is it true that parents have more rights towards sons than daughters? Do the daughters also have the right take care of the parents(be it financial or emotional) after marriage or is it only the sons who are answerable to Allah?
When raising us up my parents never differentiated me from my brother in anyway. now I want to take care of my parents when they visit me in US. Alhamdulillah they do not need any financial help. But my in laws are of the view that it is inappropriate for a father to stay at his daughter's house for a long period.They insist my father to stay at my brothers place for a long time and visit daughters only for few days. As a result my father has become hesitant about his stay at my place.
It is the only time I get to serve my parents when they come to visit us in US. Coming to US after spending so much money on travel etc.. and staying just for 10 or 15 days is not realistic. It will be of great help if you can tell me what sharia and our prophet (sallallahu alaihi wassalam ) had to say about this so that I can convey the same to my parents and make them feel better.

Answer :

In the Name of Allah, the Most Gracious, the Most Merciful.
As-salāmu ‘alaykum wa-rahmatullāhi wa-barakātuh.
In principle, the rights of the house belongs to the husband. Your husband may whole heartedly permit your parents to stay at his house for any period of time.
 It is also among the etiquettes of the guest that the host is not inconvenienced in any way for example staying for lengthy periods of time.[1] Do ensure your husband is not subdued in permitting your parents to stay for long period of time.
 And Allah Ta’āla Knows Best
