Multiple sponsors for parents' visa?

[anuts]

Is that allowed?

[peace999]

Allowed or not , it will not lead to a successful outcome. Sponsorship for a visitor visa by the host actually tells the officer the applicant does not have the financial means to fund the trip. Which ironically is a reason for denial because financial ability is considered as a tie to home country. This does however work
in some cases like children sponsoring parents or in some exigencies. But multiple sponsors will not work.
