Thanks . But does that mean that I can apply from US but I will have to enter canada from my home country, If I receive the visa grant. Please confirm I am not able to go back right now, but will b able to go back only after a month or so.It might not count as that. On B1/B2, you cannot even open a bank account. This status does not permit you to be in the US longer than a specified period of time stated in your passport. However, you can perhaps give biometrics in the US
