Actually, we did think about option 1 but then we thought if noticed, RFE aauchha vanera. In hopes of getting EAD soon, any possible RFEs aile dekhi avoid garna mann chha so we prepared explanation letter about the typo. Second option jastai notice chahi hunchha kina vane we are submitting explanation letter, tetile vaye pani RFE na aaula ki vanne hopele. Aba matlab garne ki nagarne khalko officer le determine garchha hola pachhi k submit garnu parchha vanera. In case RFE aayo vane, new corrected marriage certificate banaunai parchha hola. Aile dekhi banairakhnako lagi k garnu parchha hola vanne pani confusion vayo, original issuing authority ko details change vayeko hunale. Affidavits le hunchha ki hunna vanne pani thaha vayena. Thank you so much for your reply!
