BLGO sorority and service sorority

Im considering joining omega phi alpha which is a service sorority because community service is important to me. I have aspirations of joining an NPHC sorority after I graduate only because I do not feel that if given the opportunity right now I wouldn't meet the standards that they uphold. My question is if I join OPHIA will it hurt my chances of being invited to join a graduate chapter of an NPHC sorority? I've literally been researching for years but I'm just curious to know what actual NPHC members feel about service GLOs
