now we're getting somewhere.. All you need to buy at either Vientiane or Savannakheht is a 90 day single entry Non-O visa based on marriage.
THEN once you come in you'll get a 90 day entry stamp and when you have 30 days or less left on that you go to the immigration office and apply for your yearly extension of stay by meeting the financial requirements and submitting the correct documentation. As a rule when you apply for a yearly extension it goes under consideration for 30 days then you go back to get the year extension inked into your passport. AFTER you get that year extension inked in you can buy a re-entry permit that will let you exit/re-enter the country for the next year.
