For starters, USCIS will presume that if your marriage took place within a very short time of entry to the U.S. -- typically 90 days -- the purpose of the entry was to get married. No matter what, it's best to wait this long before the wedding.
Propane has a few advantages of gasoline, of course. It tends to burn more cleanly, itâs cheaper, etc. Still, nothing is perfect. Like any fuel, LPG/propane has some draw-backs that youâll definitely want to be aware of before you âpull the triggerâ and finally convert your car to propane.
Propane exists in its liquid form at or below its boiling point (-44Â°F) as well as when it stored under pressure. To further explain, if the temperature outside is -45Â°F, propane will be a liquid and you would be able to pour it out of a bucket. But as soon as the temperature rises to -44Â°F, the propane begins to boil and thus give off vapor. If the temperature outside is colder than -44Â°F, propane exists as a liquid.
