We are in the early stage of the K-1. Filed on August 8 and received NOA1 on August 12. My fiancée (beneficiary) is visiting for a couple of weeks. Is it ok at this point whiles she is here to add her to my stuffs such as holding joint accounts etc. or wait after the 90-day visa is issued and we are officially married and living together before we start having "joint ownership" of assets in lieu of the adjustment of status application? It gets muddy sometimes, so your inputs are always welcome.
