green card surrender - visitor visa

[tollgate0000]

hi
want to surrender green card of my father and he is based out of delhi. my brother got him the green card as he is a citizen.
should i apply for a b1 visitor visa at the time of surrender or wait for few months and then apply for b1 visa.
is it true that getting b1 visa is tougher after surrendering green card.?
reason for surrender is that he stays longer than 1yr during each visit and so want to avoid poe hassless ..

HE should apply for a B2 visa while surrendering the GC. Have him discuss specifics with the firm of Murthy in Chennai should he desire so.
