Dear one,
These are the things you need to do:

1) Read zungdu [Collection of Dharanis] once.

2) Recite the mantra DONYON SHAGPA MARPO (for yellow Amoghapasha) 4,000 times.

3) Each month do the incence puja to Padmasambhava Lhasang Namdak Choku. This is a particular offering to the guru, Buddha, yidam, dakas and dakinis and Dharma protectors. Rinpoche said this puja is good to do, but dedicate for all the Sangha who have visa issues and also please dedicate for the success of all FPMT projects, especially the Maitreya Project. This can also help for your success.

4) Do the general protector pujas and prayers regularly, especially Namtose, for your success and for all your obstacles to be removed.

5) Do the White Mahakala torma offering prayer regularly. This is very good for you and very good for visas. Make offerings such as biscuits and other things to the real White Mahakala in front of you (not a picture or statue), then offer the torma.
