She can use her bankcard to withdraw her money from her account in Canada thus she doesn,t have to change her deposit. In order to use cheques she will need a USA account as Canadian cheques will not be honored here to the best of my knowledge. RBC offers a USA account,- I,m sure other Canadian banks might too. Then, when her pension is deposited she transfers it to her USA account , writes a check and it,s done.
If she wants to cut all ties to Canada (for tax purposes) she can;t have a Canadian bank account . I don't know if she could have it direct deposited to a Dominican account,- might have to wait till she gets here to find out. Anyone who can comment on direct deposit to DR accounts?
