1.Marriage is to be worked out especially at the initial phase by showing greater patience and compromising attitude.
2. Do note either of you will have to be more accommodating to survive the marriage and if you become inflexible then marriage would not work.
3. Talk to her and convince her to wait for sometime till you obtain visa for her.
4. i am sure if you take your wife to USA and stay their together all your acrimony or misunderstanding will ebb out.
5. So best of luck to you and do try to take your wife asap to abroad.
