B2 Extention Help needed.. USCIS asked more info

[Fuhberry]

So I had applied for Visit visa extension. I am visiting my family and friends in the USA. I have no intention to live p ast my extension. I am a Dentist a foreign trained. I hold a Canadian Green card.

Reason I am in USa is to just visit and figure out if i want to pursue moving to USA in future. I had asked for an extension and I got a reply back from US Immigration. Below are the 2 questions I am bit confused about.

3.) Regulations require that a visitor for business or pleasure must establish that he or she has a residence abroad which he or she has no intention of abandoning. Submit a statement that describes what if any effect an extension of stay would have on your residence abroad.
4.Submit a statement in which you describe your intention concerning departure from the United States.

Can someone help me what they want from me? Anyone had similar question asked ? whats the appropriate reply?

Thank you

They want you to document your social and financial ties to Canada. Basically give them evidence that you have strong reasons/ties to go back to Canada to.
