Applying B2 for my in-laws while my H1B amendment is still in process

Hello All,

My H1B visa amendment is in process since oct 2017.

I am planning to apply B2 for my in-laws to visit us during this summer.

Should I wait till I get amendment process to complete to apply for B2? or Can I proceed with B2 for my in-laws with the amendment reciept? Also want to know will it have any negative impact on H1B amendment or B2 Visa.

Please suggest me.

Thanks in advance!
