My wife has a visa for the US issued in 1985 in her old passport which expired in 1993. The visa is for a none immigrant & is endorsed "multiple" & "indefinitely". We married in 1991 & the passport had her name amended on marriage and has been amended and stamped by the UK passport office.
Can she still use the old passport & it's visa stamp in conjunction with her current passport or does she need to have the visa stamp in this one?
Because of the name change, if we can/do use the old passport, would it be advisable to take our marriage certificate as additional proof of the name change?
Can anyone also give me some idea how long a tourist visa application for myself will take to come back after submission?
Many thanks
