Myself, I think matching is such a pandora's box with two categories
Just use iptw and you'll thank me for it --

Dear All
In PS matching, I am wondering about how to handle multiple categorical variables e.g. 15 variables. Each variable has multiple categories e.g. 3-5 categories. Do I have to create dummy variables,
(n-1 for each variable), for all those categorical variables before calculating propensity score?
Thanks
Pete
