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 as a liquid and a gas. At atmospheric pressure and temperatures. above â44 F, it is a non-toxic, colorless and odorless gas. Just as with natural. gas, an identifying odor is added so it can be readily detected. When contained in. an approved cylinder or tank, propane exists as a liquid and vapor. The vapor is. released from the container as a clean-burning fuel gas. Propane is 270 times. more compact as a liquid than as a gas, making it economical to store and. transport as a liquid. Approximately 90 percent of the United Statesâ propane supply is produced. domestically, while 70 percent of the remaining supply is imported from Canada. and Mexico.
