There is no point in making up evidence. If you don't have a joint lease, you need to provide other evidence of joint residence. And if there is no evidence at all, then focus on joint assets and liabilities, shared experiences, and other evidence of your relationship.
The above is intended only as general information, and does not constitute legal advice. You must speak with an attorney to discuss your individual case.
There are other ways to show bona fide marriage. A lease agreement is only one of them. Try get affidavits from your friends confirming the facts of your relationship.

A letter from your sister is good, also consider affidavits; name on bills; bank accounts; both parties on insurance; important documents tying both parties to the listed address (payroll stubs); etc.

You can get an affidavit from your sister, not just about your living arrangement, but also attesting to your bonafide marriage. Also if you husband and you receive mail there, that would be good evidence too. I agree with the other answers about providing other evidence of joint financials.
Our law firm handles matters like these and will be glad to assist.
